Welcome to FusionFall Answers. What would you like to know?

There may be a variety of reasons. One of the things that might have happened is you said a dirty word, or something close enough that the chat mods decided to ban you from chat. Another thing that might have happened is that you have an unverified e-mail address, and as such are not allowed to chat. A third possibility is that your computer or internet connection has something wrong with it, and as such you cannot use the chat box.
