Hello everybody!
I would like to build (to learn how to build) a web chat. I don't how should I start so if someone can give me tips what should I do, and than I'll search the web for how to make it and I'll make it. As I said the problem is to have the structure - what should I use. I found several chat engines, but no one fits my needs.

My needs are:

Chat rooms
private messages
without registration
SPEED!
and Administration - banning users that doesn't follow the rules of the chat.

If you have any ideas just tell me something in the form:
1.use this
2.make this
3......(something)

and I'll find a way to implement it!

Thanx in advance!

regards!
