Re: Multiblog + unique communities
HI Ken,
Just so you know I’m in the process of setting up my first WP/BP site so I’m a complete beginner and this might be bovine fecal matter.
Not sure this is what you want (or if it will even work), but it might be a workaround to get started.
You can set users to autojoin a specific bpgroup on registration, name the groups site1, site2, etc and when they signup through each sub they can be automatically joined to that group. (and automatically ‘friend’ the members of that group if you want)
That way you can differentiate the members of each site by which group they joined. Like I said, this might be bovine…… but it might work too 
Regards.
