If this is your first time as a member of a message board here is a little advice. You probably want to remain anonymous. If you choose to reveal who you are, you are better off staying away from harsh criticizm of others and being very humble about yourself. People who reveal who they are, are likely to be sending me a message asking me to delete their account.
I would simply state that I follow, or support, certain teams and leave it at that.
ALSO, at all times protect your password, I have received a few messages from people stating that others have been posting under their name. Never give out your password, membership is free, tell them to get their own.
