What is a BBM Group?
It’s a Group within the BBM Messaging app.
Ohhh ok! It's for Blackberry users right? Forgive me, but I'm unfamiliar with Blackberry devices so I didn't realize! Since this forum is for those with Apple devices, you might want to post this on our sister forum at CrackBerry.com
No it’s actually cross platform between android and iOS, since BlackBerry makes android devices now.
