We have a possible partner we'd like to cooperate with. We're thinking of the possibilty of integrating XenForo users and PHPBB users. So that the users on the PHPBB forum already have an account on our site, and doesn't need to register on our site.
Maybe creating a form of seperate style, forum categories and language based on group membership on our main site? So that our partner have a form "community" of their own.
Is any of this possible?
