True, although I can not see the point of this, except for fun, (but than again what are a lot of other ones, !explode, !switch for but fun?) maybe don't let you do !credits on other admins, because than they could just go back and forth. But that sounds bad, because what if you legitimately wanted to give creds... Maybe just let you give it to yourself, or just keep it as it is that sounds good.

Ok, how about 0 is that it is not enabled, 1 is that you can't give it to yourself, 2 you can give it to anyone, and even if you want, 3 is that you can't give to other admins.
I'm no coder, so I have no idea how hard this would be, but I doubt it would be thaat hard.
