Given the new tags page, tag wikis are yet more valuable and important. But there has been a regression in our ability to edit them.
I created the authentication tag wiki a while ago, and am still the top answerer: https://security.stackexchange.com/tags/authentication/topusers
I just tried to update it, but now my edit needs to be approved, even though I have over 2200 reputation. "You do not yet have tag wiki edit privileges. Your edit will be placed in a queue until it is peer reviewed." It says I now need "trusted user" permissions (4000 reputation).
Ironically it offers to let me approve other edits on tags where I have little rep, like forensics. Yet when I do so, and it says the approval worked, it still shows as "needs approval". Update I then tried to reproduce this, and seem to have succeeded in approving either that edit or the related edit to the tax excerpt - so perhaps I somehow misinterpreted what happened before. So at this point I can approve other tag wiki edits, but not make one of my own....
