According to the description of the copy editor badge, the requirement is for you to edit 500 posts. I have done that and I don't see the badge. If you look on the users page, you'll notice that both bmike and I have edited more than 500 posts. Why don't I have a badge?
There are a few potential reasons:
- You seem to have recently crossed over the threshold, so the badge simply hasn't been awarded yet. Some badges aren't awarded immediately, but instead with a batch script that's run daily.
- You edit a lot of tag wikis. It's possible that the /users page tracks all edits, but the badge only counts edits to posts.
- Maybe only edits to the content of a post are considered for the badge, and while you have 500 edits some are editing the tags of a question instead of the actual content of the post.
These are just speculations, but I'll bet that at least one is true. Just keep editing, you'll get it eventually :)
It has been stated in meta.so (Is the number of edits on the users page the one relevant for the edit badges?) that the edits count in the users page is not relevant for the edit badges. It is said to exclude trivial edits, but it has not been officially stated which are trivial.
Just recently a counter has been added to the right pane of the review page, which shows your progress on edits:
Reflecting the edit count on the review page to the one on the users page; I can say that retags aren't counted for badges while they are counted on the users page — just checked this.
