This Link MAY be of some help
This Link actually might be better as it addresses a very similar question
Thanks for the links! I checked them out. Looks like the Networks+ plugin website is no longer online. I have tried the BP Multi Network Plugin but, this hasn’t changed the behavior at all.
It does not appear that there is any issue with having separate users per sub site, but the page that shows the recent activity shows activity for the whole network. When I go to select all users it even shows the correct number of users for that specific subsite but then the page loads and it loads everything lol.
I was hoping there was some type of hook I could use to only show activity for users that belong to the subsite.
Side note: Wow valuser you have been on these forums for quite some time!!
if you can contact This Guy he may be able to help you. I have no expertise whatsoever – he wrote the Networks + plugin & it does work. He was always most helpful to me. Anyway all the best – i just check in on this forum occasionally – if i can offer help i try to as when i was interested many (including busy developers) helped me.
