As of right now !bid and !dkp are both case-sensitive commands. If someone does !Bid or !BID or any variants of !bid that has any form of capital letters. This is for !dkp as well.

I know people in my guild tend to use caps lock as their PTT modifier so it tends to happen that people do !BID or !DKP and they get back an error since those commands are case-sensitive. My suggestion in this case would be to make them not case sensitive if that is not too hard to do.
