I would also like to suggest some sort of a 'VERBOSE' type feature. Other networks such as DALnet has it in their services package, and basically, it could work with X. So, when set to 'ON' users who add usernames to X would get a notice in the channel via 'OPNOTICE' letting users know a user in the channel is modified via X. This would than give the administrators of the channel a chance to see who is adding/removing/suspending/banning who in the channel with X at any given time. Sometimes you can't tell when one of your administrators added somene, until its too late. I personally have suffered many mass kick/bans via X in my channel, and others have had it happen in their channels. VERBOSE gives a sense of security in your channel, whether you want it ON or OFF.

I think this was discussed before, search the forums. The final solution was: add trusted ops only.
