Editing is there too, and it doesn't work for me and many other users. I don't want anything else ruined by buggy alpha software, especially if it deletes data.

And I hope dynamic categories will be implemented and bug-fixed before any Wikis that use them are migrated. And that none of the Special Pages become unavailable or ruined; they are important for keeping a Wiki in working order.
