Greeting Buddypressians,
For the whole day i’m tryin’ to display activities from the specific hidden group in my main activities stream. I don’t want to make groups public or even private because I don’t want to users be aware of other groups. I managed to display activities from groups by adding “show_hidden=true” but it displays activities from all groups and I want to display activities only from groups where user is member. I also tried “scope=groups” but then it displays only activities from groups. I’ll be very gratefull for any kind of help or clues. Buddypress 1.5.6, WP 3.4

Thanks in advance,
Jacek K
