It's part of our new Warning System being used by the moderating team. Those who violate the rules will receive warnings. If your Warning Level is something other than (0) then you have received a warning for violating a rule. Click on the number to find out what you did wrong. Once your Warning Level reaches (5) you'll be automatically suspended for a week. Pay attention to your Warning Level. Do not post complaints about being warned - take your warning like a man and realize you did something to break the rules. A warning is just a warning. It gives us a way to correct disruptive behavior privately without having to suspend people or send PMs/emails.

Only you and the moderators can view your warnings. Here's more info about the system:

Please, just don't give us a reason to Warn you.
