Does the middle page have a purpose?

Thank you. The ones i was most concerned with was the logging in page, and the message / reply posting page. Would it be difficult to modify the code so it doesnt require a new page, for example have a javascript popup that says thank you for posting a message and sets the cookies. Might that be possible? I know i could have problems when someone has javascript off, but im sure there could be a way of stepping down.
