Need to alter MySQL

[furst]

I upgraded my v3arcade and now my permission system is broke. I asked John about it, and he told me to

Add a new field to the usergroup table called minpoststoplay, make it an INT field with a max length of 10.

Can someone tell me exactly how to do this? I really don't want to mess up my DB because I'm very unfamiliar with MySQL.

ALTER TABLE usergroup ADD minpoststoplay INT( 10 ) NOT NULL
