[raises hand] feature request for "Reject All" and "Accept All", or "Set all to Reject"
It's confusing that the default on each is "Do Nothing" but also "Notify user if action is taken". First of all, if the majority of these users are actually spam, perhaps the default should be Reject. Second, it's weird to have multiple users selected as "do nothing" and then the action is "Process Users". Perhaps "Leave in Queue/Limbo" is clearer.
