Dunno why I've not done this before, but here is a list of commands you can use in our chatbox...

/clear or /cls = clears the chatbox (admin only)

/me + message = writes a message in third person (eg /me wanders off will show up as @Lunarwolf wanders off )

/away = marks yourself as away status

/away + message = leaves a message giving the reason you are away

/abs + message = identical to away+message

[url= direct url link] name of site [/url] = links to a website. (EG: google will simply show "google" in the chat-box but clicking on it will go to the specified url of http://www.google.co.uk)

Inserting a picture: in [] type the word IMG then the direct url of the website with the picture on followed by /IMG within []. Be aware that the image you insert into the chatbox will be unaltered, so may be pretty big. Avoid larger pictures.
