Who's bright idea was the MASS ACTION stuff? Unless you have massive negative comments in your journal I don't see the point of it, and implementing it kinda means that Abuse isn't doing its job. Most of us will never use it at all either. If it has some other usefulness besides the obvious, a FAQ would be helpful. Otherwise its just a redundant tool that will just sit there.
Just two things I think that could be omitted if your trying to streamline LJ.
