phpBB and vBulletin users bridge

[Ethelbert]

I want to join with one site. My forum is on vbulletin and another one is in phpBB. Everything what I want is have the same users' table. Is there any way how can I have two different boards with the same users?

Which code should I use for user registration and where it has to be posted?

It would be rather hard due to two separate login methods, plus different ways at parsing passwords.

I do beleive this would take pretty much reprogramming either board and every thing that has to do with the users.
