and something is going wrong.......
I ask for GetChat like
code:GetChat("205.147.005.037", "/cgi-bin/livechat.pl");
Now......I've found that the problem lies within the while-loop. So if anybody can help me with this. I'd be grateful.
This is just to get familiar with programming multiplayer......so don't refer me to another board. Thanks in advance.....
the address is just for general purpose....to see if it's working, since my server will look like that (though THAT address is real)

Dance with me......
