Just trying out wordpress for the first time and it seems great.
Two features that would be very cool, I think, are to have:
->Category RSS feeds. Right now the rss feed seems to be for the whole site. But I'd love to see Category specific feeds.
->Category locking. I'd like users to be able to post on wordpress, but only in the categories in which they are allowed.
My guess is these two things are probably hackable without too much work. But if someone has a quick fix for me, I'd much appreciate it.
