@ray – i really appreciate this. it’s all clear to me now. I can now manually hide the group forum in bbpress (irregardless of public or private or hidden group). Its quite basic but works fine i.e. group members must go their group site to have access to the group forum.. which is cool btw.
In step #2 above:
How do we make sure that all new group forums are automatically added into the forum category? At the moment, its added as another forum, so we have to manually change this as child to the bbpress forum category for group created in Step #2.
Thanks again for your meticulous help & instructions abv.
