Sorry, it is not possible by now.

but is there a way to bridge so that when users buy a class they get access to a certain category or set of forums?

this is essential for any interactive class

We do not have discussion forums or chat type feature but you might integrate third-party extensions for this. Many of our users use Kuena forum. It should work well.

yes so it looks like no discussion forums or chat type features?
Like does it integrate with phpbb3 or Kunena?
