Thats the normal cgi chat code and I have a few questions concerning it:
-Is it possible to change background and other colors?
-Is it possible to (when click submit) to open it in the same window...completely resized to serve as a gamechat?
-When I first logged in everything was fine, I modified the above code to get the players name and "force" it to use it in the chat, is it possible to end the session of a username? if so i would like to put a logout button in the chat too.

Thanks in advance, easy and fast chat rocks ^^ (now just modify it o.O)

-Is it possible to change background and other colors? .. YES since it's just a form..
-Is it possible to (when click submit) to open it in the same window...completely resized to serve as a gamechat? .. YES by using Javascript..
-When I first logged in everything was fine, I modified the above code to get the players name and "force" it to use it in the chat, is it possible to end the session of a username? if so i would like to put a logout button in the chat too. ... Huh..? I don't understand..


Background color :
(By adding style="background-color:yellow;")
<form target="entropychat" action="http://online.trap17.com:2084/" style="background-color:yellow;">
Nick Name: <input type="text" name="nick" value="" size="20">
<input type="hidden" name="channel" value="online.trap17.com">
<input type="submit" value="Enter Chat">
</form>


Open in Same Window :
(By changing your target to "_self")
<form target="_self" action="http://online.trap17.com:2084/" style="background-color:yellow;">
Nick Name: <input type="text" name="nick" value="" size="20">
<input type="hidden" name="channel" value="online.trap17.com">
<input type="submit" value="Enter Chat">
</form>

As for your 3rd question, I believe it's the part http://online.trap17.com:2084/ that controls the nickname.
That script in http://online.trap17.com:2084/ should be configured to accept the nickname and carry the nickname into the script for use..


Hope all these helps...
