I think that unactivated profiles should not be listed with profiles that have been activated and are ready to be approved. They should have their own list. becuase we don't really need to go through them until they are active.
Also, when a profile is approved it should automatically be removed from the list or a "check all" button a the bottom of the page with option to approve all that are checked.
I am not sure if this should be in a features section...but should be implemented.
Can Ip's be listed with the profiles that need to be approved. This way one can see if a user is signing up with multiple usernames. would be one way to have heads up on spammers.
