Well that is th right way to do it, either via PIN or email. So email your friend first saying "This is (yourname) and I am about to send you an invite to join my BB Messenger group. So you'll know it is me, I am send you this email first, blah blah."

Of course, if you have your BB Messenger setup correctly first with your name, your friend will see that ithe invite is from you.

And remember, only your friends with a BlackBerry can use or join your BB Messenger group because the BBM only communicates via PIN. You can't add someone who doesn't have a BB.
