!padan - To send an announcement to a specific player.
!forcerules - Slap Sylar. :P
Also, making !adan sendclientmessagetoplayer (was it?) too would be a good idea, so in case anyone misses the sent message, they can scroll up to see.
Interesting suggestions, although the only one that I really like is the showrules command, which I will put in 1.1 :)
It was Enigma that liked the first suggestion. And he's too lazy assed to note it down! :P
