I'm not sure why it loads a separate script, but I do remember someone in staff tried to move it to a different chat message page (where it didn't work). Perhaps it has to be like that to work? You'd have to ask Joey really.

There's an example of the the chat commands code here (the stuff under the last comment is the commands) and there's some more commands that you can use in RuneScape Wiki's chat here, with their coding here. 90% of those commands sort of require you to have a RuneScape game account but something like  give you an example of what it might look like.

I'll see if I can figure out how to get something like /wecome username working though.
