Decreasing Your Warn Level:
Over time, your warn level can be decreased. If you make useful and helpful posts, the moderators will notice and will reward you by lowering your warn level. After at least a month (30 days), if you believe that you deserve a warn reduction, send a message to any staff member so that we can review your posts and make a decision to lower your warn level or not.
Besides that, if you feel that your latest warn was a mistake, you can contact the mod who gave it, and, in case the moderator does not change your warn, you may grovel at an administrator's feet, who will either review your warn [him|her]self (it's entirely possible that the warn will still stand) or get the whole staff to discuss the matter.
