Great Kyle thanks.
I have totally nailed this and feel I should share. My use is basically admins and users. 1 bunch of admins are connected to all users. All admins are connected to all admins (auto actions for team - user and team - team)
I got the lift off from this post:
www.joomlapolis.com/forum/153-professional-member-support/219025-solved-cb-conditional-show-tab-only-for-profile-owner?start=6
(essential settings for hiding showing when in own profile)
and CB Activity module saved the day!fitted those comment fields in also.
Activity tab is only viewable for profile owner. This saves being worried about user posting on admins wall - as viewable to everybody, in their streams. Yet I took activity tab away from all admins in the end. I inserted the comment field in a comment tab for admins connected to users. So users can comment but this remains on the profile of the admin connected to the user. These admins can make statements on their profile also - no need for the wall/blog/book.
Suppose the last bit of brilliance was creating a profile I called system. This is connected to all admins. Has it's own comment tab with the comment field and shows the Activity module. Admins can all comment privately to each other in this profile and reply to users on the activity module at the same time. Sweet. Activity module is available to all admins in any profile.
Admins connected to all users can post on stream and goes to all users. Nice will save a load of emailing. And if normal admin posts on the stream it's private to admins. Users can't access profiles their not connected to so normal admins can post on any stream.
There's more to it but that's the jist. So happy I got the core function sorted was bogged down for 4 or 5 days with this. Onwards..Thanks again for help Kyle, the support got me through
till next time..
