@Devonrevenge: Aha, I thought you meant an C++ executable that did this.
It could be possible by sending PM's but I think I should ask Twicker's approvation for this, as this could cause spam, exceptionally for users who do NOT have this extension.
Also this won't work over groups.
* Careful: Purely fictional terminology over *
For these purposes it's better to use a dynamic messaging system like IRC instead of using a "static" one like the PM system here.
What makes them dynamic/static?
Simple: Memory.
The term I used, "Dynamic messaging" means: If you're online, you'll get the message. I won't save a copy to send you again later, and unless you keep logs I won't save it on the server.
The "Static messaging" means: Hey, this user sent you a message. If you go offline I'll notify about other messages, don't worry. But we will also save these messages to your PM Inbox folder. I don't know how much free memory is there, so be careful about this, you may fuck us up.
And that's why I don't want to do it on my own, it's better if Twicker makes a Python applet for a javascript chat.
Because Twicker, I know you use Python for this :3
EDIT: Oh shit I meant all another thing, but I'll leave the above sentences for the future readers to laugh at.
In fact I'm used to visit a website who was made in Python ( with this server:
