I was responding about a moodlerooms user group. There are ANGEL and WebCT usergroups on the list @ http://www.blackboard.com/Platforms/Learn/Resources/Community-Programs/Meet-Your-Peers/Listservs/By-Platform.aspx
I said that I emailed them to see if they were going to add one for Moodle since they were now supporting Moodle through Moodlerooms and NetSpot.
We have both Blackboard and Moodle at our school. So I am a member of a couple of users groups on the list. I was not that interested in a Moodle group through them as I was hearing what their response would be to the request.
My guess is that there will be something similar to the Bb, ANGEL and WebCT groups but hosted by the 2 Moodle Partners themselves.
