nice clean dialogue there GrimReaper as per your norm.. i have one suggestion howver for you that you may wish to look at. for the ban mask .. you currently select a number .. but it might be prudent to include somewhere on the dialogue the format of the number ...
ie !ident@hostmask , !@.isp , etc etc against the number so they know what type of ban does what when they are selecting.
otherwise .. sweeeeeeet.. gets a 10 and a like
