Use the formatting buttons to the left of the message area when making a reply or new post. Again, though, this is an option that can be turned off. If you don't see the buttons, then the board owner has disabled this feature. Your rank is based on the number of posts you have made on this particular board. The more posts, the higher your rank will become.
Users can rate each topic from one to five.
If you violated some of our rules and procedures, then it's your own damn fault. Your only recourse would be to email the board owner and plead your case. No, you can't. As stated in our terms of agreement when you create an account, you can and will be banned for inappropriate conduct.
