Integrate forum PHP BB or other in cscart multivendor -- 2

Hello we are developing a site made in multivendor cs-cart. We would need to integrate a forum only for sellers who have the same login credentials as sellers. * Signing up to CS Cart automatically creates a PhpBB account * Automatic login to PhpBB when logging in from CS Cart without having to log in to PhpBB * Synchronized CS Cart and current PhpBB users (suppliers only) * Logout from PhpBB redirects to cart logout CS * Change PhpBB Account Redirect to Change Cart Profile CS * Change PhpBB Password Redirect to Change Cart Profile CS * Change Cart Profile CS also updates PhpBB

or

CS Cart subscription automatically creates a PhpBB account * Automatic login to PhpBB when logging in from CS Cart without having to log in to PhpBB Synchronized CS Cart and current PhpBB users (suppliers only)
The ability to change your password or change your profile from PHPbb is eliminated
