Having same issue and have also posted a similar question here.
We found a solution of a sort.
What you need to do is include an automatic private message send to all group members except the person posting the topic. This private message then gets hooked in to the notification system and lets the user know they have a new message.
Nice! Would you mind sharing in a bit more detail how you achieved this?
I would say sure no prob unfortunately though the role I played was suggesting that when a new topic was posted a private message is sent to the members. The actual implementation was done by my developer…will see if I can get him to post a how to here.
Hello guys im in the same boat, I hope this feature will be implemented soon.
Hi
Can make a plugin for Buddypress so that the forum sends private messages to group users. This will then cause the notification system to pick up the message and show it in the grey WordPress/Buddypress notification bar. Your forum notification problem solved for only £15.
Let me know if you are interested and we will build it
