I have found a possible integration issue between groups and BB Forum. When a forum post appears on the announcements page, it is possible to comment on it. This comment is not added to the forum post, thus creating possible confusion and/or de-sync issues.

You will have to provide more information. BuddyPress doesn’t have an announcement page, are you using a plugin that generates this page and if so, what plugin?, I’m not sure if this is something special or a normal group activity item.

As to your reference to “BB Forum”, do you mean bbPress or some other plugin and if the latter, what plugin?
