In other forum posts 3 weeks ago, an official representative has stated the following: "Hi guys, sorry you are frustrated, I understand it's been promised in
the past. I can tell you with 100% confidence we are actively working
on MMS for you guys - please email me if you would like to discuss
further & more details."
When pressed for a time frame 2 weeks ago, Ted (the official Rep) stated, "Sure! Early next year - hope that helps"
Hopefully that helps answer your question/feature request.
