Soooooooooo…
Is their no support for this?
Three months and no response? Awesome!
No need for sarcasm, let not your pink hair turn red
Per my last check in a test install of multi-author blog, existing users – from contributors to Admins – are automatically listed as Members. Of course the dropdown for “Last Active” might show only the Admin until your users sign up again since sitewide activity will only be recroded by BuddyPress after it is activated. You can see all your existing members in dropdown selection “Newest Registered”
Edit – there’s also this plugin but haven’t tested it for latest BP/WP versions http://teleogistic.net/code/buddypress/bp-import-blog-activity/
So basically the answer is yes, but they won’t be visible in the activity feed until after they login again? That makes sense.
I just found out the user contributor gallery the site is set with (essentially the whole purpose of the website) was discontinued by the developer, so I need to find another solution and get that worked out before worrying about BuddyPress. I’ve heard mention of NextGen being an option, but I’ve found no way to allow Subscribers/Members the ability to upload to predefined galleries.
