Login Modification
 

Was looking into purchasing vBulletin to use on a website I am working on but I have a login system created for it already that clients log into. I heard it takes a bit of work to incorporate my login system into the vBulletin message board. So I have 2 questions,

1.) Can I let a user login anywhere on my site and then let them access the message board and not have to make them login again?
2.) If so what is involved? Do I need to just set a session up for that user?

Any help on this would be great as I don't want to waste the money on purchasing this software if I can't do what I want.

Thanks for your time and any help you can provide,

Jeremy
