The C-box is basically your freedom on WCC. You can talk in all caps, holler, shout, exclaim, anything you like as long as it isn't rude or inappropriate. :) You can rant in the C-Box, keep it clean though. You can chit-chat with your friends or other WCC users. Another thing, you can advertise. Advertise a cat for adoption, etc. Limit one advertisement per ten minutes though, don't flood. :P Basically, the only rules for the C-Box are don't spam, don't flood, and don't be rude, mean, or inappropriate. :D
