Topic: CSRF for markread, markforumread, etc.?
Perhaps these actions should get CSRF tokens, as with logout and some of the moderator tools? Currently someone could trick other users into performing such actions by embedding them in [img] tags, for instance. It's not exactly a security vulnerability, but it would certainly be a nuisance, and there are unfortunately a great deal of people who go out of their way to be nuisances on forums.
