Hi all,
I’ve a platform website, with a wp forum, buddypress, classifieds, and I activated wp multisite mode.

I’m thinking I could have some advantages installing BUDDYPRESS MULTISITE, meaning having buddypress in all the mini websites of my network…..but I don’t know exactly which ones might be the features.

I’ll try here to say some thoughts;
with buddypress multisite:
– can the buddypress members of the main site leave comments and communicate with the owner of a sub website who use some buddypress features in his website?

For instance:
people register to the main site, so they have their own profile: their first aim is to communicate into the forum, which in my case is simple press.
Then these members go to some subsites of the newtwork, let’s say to a sponsor website and he create some buddypress activities: can the members interact in that page?

I’m just wondering what exactly mean having buddypress multisite.

And the last thing: for having buddypress all over the main site and subsites should I follow the ( F ) procedure of the following guide?
