Is there a list of privileges that users have on any Stack Exchange chat rooms, and which lists the minimum reputation required for each privilege?

If such list doesn't exist, what is the reputation required for the chat privileges?

How are chat privileges granted?

Stack Overflow and Meta Stack Exchange each have their own chat; the rest of the network (Stack Overflow in non-English languages, Super User, Server Fault, [other topic] Stack Exchange, etc.) has a combined chat site (Stack Exchange chat).

For non-moderator users, privileges apply based on your total reputation on the associated site(s):

  • On Stack Overflow and Meta Stack Exchange chat, privileges apply based on your reputation or moderator status on the associated site.
  • On the combined Stack Exchange chat site, privileges apply based on your total reputation over all sites. If you have the global association bonus rights, only profiles where you have at least 200 reputation count towards this sum, though all reputation (including bonus reputation) on those sites count.

Moderators of any Stack Exchange site will have moderator privileges on Stack Exchange chat and on the respective site-specific chat server on which they're a moderator:

Site Moderated Stack Exchange chat Stack Overflow chat Meta Stack Exchange chat
Stack Overflow

Meta Stack Exchange

All other SE sites

Note that moderator privileges do not apply to certain special types of rooms known as moderated private rooms - see the Special Note at the bottom.

What are the privilege levels?

The privilege levels are:

  • public: read messages in non-private rooms
  • registered: talk in any room if invited
  • 20 reputation: participation (specifically, talking)
  • 100 reputation:
    1. bookmark a conversation
    2. create a public room
  • 1,000 reputation:
    1. create a gallery room, i.e., a room where messages are public but only specific users can talk
    2. be able to change the access level of a room where you're a room owner from public to gallery and vice versa
  • 10,000 reputation:
    1. be notified of spam/offensive flags (the number of active flags appears in a circle on your gravatar)
    2. view deleted rooms (read access only if allowed).
  • room owner:
    1. edit the room name and description
    2. pin a message (a pin is a super-star)
    3. remove stars from messages
    4. grant explicit read access
    5. grant explicit write access to users with at least 20 reputation
    6. change the access level of the room from public to gallery and vice versa (only if you have 1,000+ rep or are a moderator)
    7. grant and remove room ownership
    8. create and remove feeds
    9. move messages to any other room (provided it's not private or deleted)
    10. schedule events
    11. kick-mute users
    12. put room in timeout (must specify a reason)
    13. view histories of deleted messages (provided they have a link to the message's history, which is only shown in the live room, and the history hasn't been purged)
  • ♦︎ moderator (on chat.SE, moderator on any site, even SO or MSE; your parent site must be set to one where you're a moderator; doesn't apply to "moderated private rooms" - see the Special Note below):
    1. all the above[1]
    2. edit or delete any message at any time
    3. purge a message's history
    4. move messages to private rooms where one has access (see the next section header)
    5. view moderator flags
    6. mark flags as valid or invalid
    7. grant explicit write access to all users even if they don't have 20 reputation
    8. super-ping users (ping users even if they're not pingable in the room or don't have a chat profile)
    9. ban users from chat
    10. annotate users
    11. destroy chat users[2]
    12. anonymize a user's messages to their user ID[2]
    13. put a room in timeout without having to specify a reason
    14. freeze/unfreeze room
    15. delete/undelete room, list deleted rooms
    16. be immune to being kicked or suspended from chat
    17. remove the restriction on creating new rooms for a user who has been kicked three times
    18. view a list of recent chat flags raised across all rooms
  • ♦︎ moderator on the site associated with the chat room[3]:
    1. create private rooms (where only specific users can read content)
    2. see and access private rooms
    3. change the access level of the room from public or gallery to private
    4. change which site is associated with the room
    5. view which user raised a spam/offensive flag on a message (provided that the moderator is in the room where the flag was raised and viewed the flag while it was active)

[1] When moderators create a scheduled event for the chat room associated with the SE site where they are moderators, the event will be published also in the main site.

[2] Moderators can only take these actions on users who've posted fewer than 1,000 messages. For users who've posted 1,000 or more messages, only Stack Exchange developers can take these actions. Developers also have access to a modified anonymize messages tool that removes the user's ID from public view.

[3] For rooms which don't have a parent site set (i.e., are general network rooms), being a moderator anywhere on the network will give you these privileges there as well.

Special Note: Moderated private rooms

To facilitate internal discussion of moderation, most moderator tools are disabled in this special type of private room. One such chat room is the Teachers' Lounge (note the "hollow diamond"):

Hollow diamond for Teachers' Lounge

These are similar to private rooms but operate differently from other private chat rooms:

  • Only a designated list of "room moderators" have access to the full list of moderator and room owner privileges described above, aside from being able to grant and remove room ownership.
  • Only Stack Exchange staff can create this special room type and change the list of room owners and room moderators.
  • Users with moderator privileges who aren't explicitly room owners or room moderators will only have the privileges given to chat users with 10,000+ reputation above and the ability to super-ping users (moderator privilege 8 above).

(Within the Teachers' Lounge, room moderators are decided by election within the Moderators' Team.)


  • The privileges page covers the big ones too: participation, create a room, create a gallery Apr 17, 2011 at 23:24
  • 10K users should not then see the "blue badge" that reports there are flagged posts. Is that correct?

  • @kiamlaluno: That's an undocumented feature. I've made that answer CW so it can serve as a chat privilege FAQ. One thing I don't know is what reputation is taken into account on chat.SE: the total amongst all the relevant sites? or the largest on any relevant site? Apr 18, 2011 at 7:21
  • I've added some owner and mod features, I'm not 100% sure if I got the differences between owner and mod right. Apr 18, 2011 at 13:36
  • I am getting blue bubbles in the English chatroom; I have 9500ish rep on English, but about 10500 on all SE sites. I think it is related to total rep on SE? Apr 18, 2011 at 13:48
  • @Cerberus - Yes, this is correct. More accurately, these stats are related to your chat user. Notably, this applies to moderator accounts: If your chat user has a parent account of a site where you're not a mod, then you won't get moderator privileges. Dec 2, 2011 at 17:09
