OK, this isn't a support issue as much as a feature request.
I would like to meld this plugin with Mail Chimp integration. Crazy, I know, but hear me out.
For my service, the BP Group is a very powerful marketing tool. One of those tools is email. Group email is nice, but limited -- no html and it doesn't link to the other groups an Admin may be running.
But, imagine if there was an option to have any group member be signed up to the admin's Mail Chimp account... I know, right? Now, all of an admin's groups (users on my site generally have more than one) are in their Mail Chimp, likely separated by group specific lists. Now, the admin has the option of sending mail out to all members of all of their groups, or to individual members. And, those emails will be rich, HTML emails with open and click tracking.
You all need to make this happen. It would be awesome.
