YOU page bugs
A couple of bugs on the settings pages - first off, clicking on change email>manage alerts just throws you back to "update your profile"...unless I'm missing something, I don't see any place to manage alerts from that. (Clicking on the link up top to manage email alerts does work, however) I could be way off-base, but it seems like the WATCHLIST object (as opposed to, say, EMAIL) is maybe invalid or something like that?
Also, I have several collaborations, but my collaborations tab shows 1 collabs (and it only shows that 1 after joining another - it displayed 0 for a while).
Oh, and on the way here I noticed that when you go to Submit>Bug, instead of taking you there directly you go to Community>Help. Dunno if that's intentional or not. =]
