CustomChat: A not-so-private chat-server

I've worked on this for a bit, and I need testing along the way if I want this to get better, so here we are. I've begun work on a new chat-server for SmileBASIC Source for private use, which I've codenamed rather simply "CustomChat". I'm thinking of better names, so this could change at any time. As of right now, this is alpha software, so don't be suprised if some things act rather stange, or don't even work. The major things not implemented right now is commands and privileges, so please leave me alone about this. Just a very important note for you super secure people. This chat server does require your PHPSESSID (which is your session token) in order to verify users. I'm sort of breaking my own rule, since your cookie is sacred, but this is to prevent users acting like other users, which is a major no-no in my books (this could cause damage to my server and to people's reputation). I promise you that I do not store, log, or otherwise use your session or ChatAuth token for malicious purpoes. I would release the source code as proof, but this is under development, and I need to refactor a bunch once I get features added. To join the server, you'll need to go to your ChatJS (http://smilebasicsource.com/editor?type=chat) and copy the script located at http://pastebin.com/raw/zsmCm3DA to there. Save, then go to http://smilebasicsource.com/chat?server=shadowtech-dev.cf:45695 ... PROFIT! If you have bugs, please send them to me in a Site PM, especially if it has to do with security. You can suggest features and discuss the chatroom here, of course. I hope you think this isn't as useless as the rest of the crap I make. EDIT: It's also unmoderated for now, so free speech can be done there. Just please, no criminal activity. That's it.
