Using a custom template

[Jaime82]

I created a custom template and I'm trying to use it for a chat room I have set up so I can integrate Vbulletin and my chat room to use the same usernames and passwords. I have the Vbulletin login form so the users can login using their Vbulletin username and password and want the users to be forwarded to my custom template I created after they login. Does anyone know how to do this?

Thank you in Advance!
