Is it possible to know the number of edits I made on Stack Overflow?
For example, is there a way to know our status towards reaching the copy editor badge?
Aside from counting your revisions of other's posts by hand (or using the http://data.stackexchange.com, e.g., this query) you cannot tell how far along you are from the
Editors tab because that number includes edits you have made to your own posts.
The count on that tab also doesn't include (approved) edits that you made prior to gaining 2000 rep, which do count towards Strunk and White anyway, I believe.
Progress towards Copy Editor, and some other badges, is now displayed on the
/review page. (Well, technically, it isn't there right now, because the team is beta-testing a new format for
/review. But they've promised to bring it back soon.)
