I can deliver this at least saturday evening. If I got your picture right. (I'm belgian, for your information).
So what you want is a little menu, with login form, that, once filled in, it will automaticly login into vbulletin forum? Also a link to register on the vbulletin forum? If I got wrong please let me know, so I can see if it is still in my capabilities.
Thank you in advantage
