Instead of banning on ident, admins and above can now lookup the raw IP and ban from that.
Members area has a new option "Lookup Name2IP" which takes a partial name (Case-sentitive, sorry) and retrieves the IP of users with that name in any chat.
To ban such IPs you take the IP, eg 123.234.23.12, and cuts away the last 1 or 2 sections, eg 123.234.23 or 123.234, and inputs that as you would a normal permban in Options (gui_opt.php).
Makes sense? Probably not...
