I don't have the code with me on this machine... but towards the top of the new template it'll say
$aas = 1;
Set that to 0 if you are not using AAS.

Don't alter the code.... just substitute your chat room id number.
There should be an "auto login = yes" type parameter in there, that's what signs them in automatically.
