Can my board's registration form work across platforms & be used for my main site too

Hello, I saw your Necrotania site. It looks like your site is ALL VBulletin without a separate site attached, like mine. I wouldn't mind having users click on the "register here" link on my site, and then they can be redirected to VBulletin's registration & p/word recovery form, and then they would be registered users. BUT, BUT, once they register in VBulletin, their user name won't likely appear in the location where it says: "rated by"in the main part of the site. That is, the name of the user submitting the ratings in the main part of the site, appears in certain areas of the main site in association with their submitted rating, and all of the other things the main part of the site controls--like limiting a user to one rating for the same judge, etc.. If they submit another rating for the same judge w/in 5 minutes of submitting the first one, the script erases the previous one, and so on... This prevents the same username from stacking ratings over and over.

Thanks for your reply, I think I'm half way there if I keep getting ideas from others.
