Also, if you use SourceBans to track bans and still may wish occasionally to have ULX ban from just one server, instead of deleting the line that has !ban in it...simply change the !ban to !uban (ULX ban) or something like that.
Also, you stated you got the Sourcebans file from here...mind pointing me to which post/file worked?
I tried releasing 2 I think, and never got the results if it worked or not.
(Or, was it Megiddo's release? - think he released some after I did)
