It would be very helpful if in the users panel there was a listing fo the number of comments posted by registered users rather than (or perhaps in addition to) the number of posts. I think most blogs have a much smaller number of people authorized to post than to comment. I'd like to be able to tell who are the most active commenters--and if someone has *ever* commented. That would also help with housekeeping since I get a lot of fake registrations (most from .ru domains) traing to spam my blog. Thus far they've been blocked by the spam add-ons I'm using, but they still clutter up the user list.
