Hi Greg,
I was wondering whether group PMs were possible? I am thinking basically like a private discussion thread for the purposes of planning meetups, etc, that everyone can respond to and see everyone else's responses. In the past for planning meetups we have just collected email addresses and then done the planning via an email list, but it might be kind of nice to have everything gathered into a single PM thread. Just a thought. I don't know how feasible this is though.
