There are three main types of privilege thresholds (sorted from high to low):
Some sites have a unique privilege (level) schema:
Additionally, per-site metas do not have reputation, deriving their reputation straight from their corresponding main site (with some caching).
The three main types are covered in the table below. Some minor changes to individual sites are indicated with a † in the table and explained further below.

† Some site-specific change applies (see "Site-specific changes" below)
- The privilege does not apply (no elections or advertisements on this stage)
♦ Privilege is purely reputation-based; being a ♦ moderator does not suffice
¹ post more than eight hyperlinks (50 on Skeptics); less rate limiting; post images (not a new-user restriction on every site)
² +100 reputation on any associated account once you reached this on any site
³ see and cast close and reopen votes on own questions
⁴ access the first-posts, late-answers, and triage (SO only) review queues
⁵ edit posts of others without review; access suggested-edits, low-quality, and help-and-improvement (SO only) review queues
⁶ the website link in your profile has a rel=nofollow attribute if you have less than 2000 reputation, to make it not count for SEO purposes
⁷ see deleted posts, reviews of others; moderator tools (various information); vote to delete questions two days after closure
⁸ edit tag wikis without review; vote to delete negatively scoring answers; vote to delete closed questions with −3 or lower score without delay
- At the moment, only Stack Overflow, Mathematics, and Meta Stack Exchange require new users to go through a tutorial before being allowed to ask.
Stack Overflow for Teams users can participate in Meta Stack Overflow with just 1 reputation. Additionally, some sites allow 1-rep users to participate in meta. The list of sites may change, but currently they are:
On all other sites except localized sites, you can ask a question about your own post on the site's per-site meta with just 1 reputation.
- Commenting everywhere on Meta Stack Exchange is already allowed at 5 reputation. On Stack Apps, there is no threshold at all.
- Downvoting on Meta Stack Exchange is allowed at 100 reputation, not 125.
- The First Posts and Late Answers review queues don't exist on Meta Stack Exchange (and all per-site metas), so on Meta Stack Exchange, the minimum requirement to access any review queue is 2,000. (For this reason, the privilege page on this site states that 2,000 is the minimum requirement.)
- Tag creation on Stack Overflow requires 1500 reputation. On Mathematics, it requires 1000 reputation. On Meta Stack Exchange, it requires 500 reputation. On Stack Apps, it only requires 99 reputation.
- Running for Stack Overflow moderator requires 3000 reputation and certain badges. On Mathematics, the minimum reputation is 1000.
Privileges not tied to a specific threshold
- To answer protected questions, you need to gain 10 reputation on the site – the association bonus does not count. In other words, the reputation threshold for answering protected questions if you have the bonus is 110, not 10. (Being a ♦ moderator does not suffice.)
- This does not apply on per-site metas, where you can answer protected questions if you have at least 10 rep on the main site, even if you earned it through the association bonus. (Again, being a ♦ moderator won't allow you to answer unless you have the required rep.)
- For every 1,000 reputation after gaining the moderator-tools privilege, you gain another delete vote.
- For every 2,000 reputation, you get one bonus flag per day. (You also gain bonus flags for casting helpful flags.) (Flags are capped at 100 per day for comments and 100 per day for posts.)
- If you have a gold tag badge for a certain tag, you can bindingly close and reopen questions using that tag as duplicates, and can modify the duplicate links on such questions, unless you edited the tags.
- Having a network-wide flair requires at least 200 rep on a specific site; having ♦ moderator or staff rights does not confer this ability.
- Only moderators and staff members may add, remove, or change red ("moderator-only") tags (e.g. status-completed) on meta questions.
- Stack Exchange staff members have the ability to edit tags on any site without having to submit it as a suggested edit, and can modify moderator-only red tags on meta sites without needing to be a moderator.
When reputation thresholds change
When a site moves from one phase to another, there is no grandfathering of privileges of any kind. You'll immediately be held to the new thresholds and lose any privileges you no longer qualify for.
There are three chat domains:
- Stack Overflow
- Meta Stack Exchange
- Stack Exchange (everything else)
Your chat privileges are based on your reputation in the respective domain. Stack Overflow Chat and Meta Stack Exchange Chat use your reputation on the respective sites. The algorithm for calculating reputation on Stack Exchange Chat is a little more complicated:
If you have at least 20 reputation on a single site but lack the network-wide association bonus rights, your SE chat reputation will simply be the sum of all your reputation on all sites.
If you do have the association bonus rights, your SE chat reputation will be the sum of your reputation of all accounts on which you have at least 200 reputation.
If you don't have at least 20 reputation on a single site, your SE chat reputation will be equal to the sum of your rep on all sites, minus the number of sites on which you have accounts, plus 1.
The first and third criterion were implemented to ensure that in order for users to talk in chat, they must have at least 20 reputation on a single site, or have earned 20 aggregate rep points overall on different sites (only counting the default 1 for signing up once).
Reputation earned on sites with site-specific chat servers (Stack Overflow and Meta Stack Exchange) does count toward the total reputation earned for the general Stack Exchange chat server.
Note that it may take a few hours for your chat reputation to update on all chat servers, so you may have enough rep for a privilege but not have it because your chat profile hasn't updated yet.
