If I see a typo on a privilege description page (or anywhere else), am I expected to inform moderators somehow? Or have I an opportunity to suggest these edits?
Have I an opportunity to suggest these edits?
As far as I know we can not suggest edits on privileges page. You can inform it here (Meta Stack Overflow.).
(or anywhere else)
But if you are talking about question or answer you can edit it or suggest edit for it.
@Popular Demand answered: You can edit privileges on MSO privileges pages.
Temporarily we are allowing all users on meta with more than 2000 reputation to edit the wikis (of privileges), we will then use these wikis as the global default wikis for all sites.
Note: Since the post is too old and they used Temporarily, the reputation limit may be changed.
The privilege pages are wikis. The "master" copies are located here, at MSO, where they're editable. Changes made to the MSO versions are pushed to the other sites intermittently.
