There are four main types of privilege thresholds (sorted from high to low):
public betas and graduated sites without a design (example)
Private Betas and this Harvard University site.
Except for Ask Patents, these are covered in the below table. See further below for changes to individual sites.

† Some site-specific change applies (see below)
- The privilege does not apply (no elections or advertisements on this stage)
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 expanded user card; see up and downvotes separately (after clicking)
⁶ edit posts of others without review; access suggested-edits, low-quality, and help-and-improvement (SO only) review queues
⁷ 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
⁸ see deleted posts, reviews of others; moderator tools (various information); vote to delete questions two days after closure
⁹ edit tag wikis without review; vote to delete negatively scoring answers; vote to delete questions with −3 or lower score without delay
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.
- 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.
- 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.
- Every 1,000 reputation after the moderator-tools privilege, you gain another delete vote.
- 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.)
- Provided you have enough reputation to vote to close, if you have a gold tag badge for a certain tag, you can bindingly close questions using that tag as duplicates, and can modify the duplicate links on such questions, unless you edited the tags.
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 19 aggregate rep points overall on different sites (not including the default 1 for signing up).
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.
