need help with database
 

i got a forums and i got a game on my website
i am using 2 database one for the game one for the forums
how can i make it so that if someones sign up to the game/forums
they sign up to both the forums or game?

You need to write a plugin that enters their user data into the game site at the same time you enter the user data into vbulletin. And vice versa.

hmm
is there any tut's or any one thats knows how to do this that could help me :O

That would be difficult to do since every site would be different (a joomla site is done different than a wordpress site is done different than my tracker site, etc.) I can suggest you look around the hook location "register_addmember_complete" for where you would probably add your code to the vbulletin site, but I have no idea what to suggest for your site.
