Okay, so update, the word from the back room:

There were very few sets actually send MAC and most were aborted by instruction from the server lacking this platforms participation. Remember we need 10 different MACs returning a valid result to make up a quorum.

An imminent project launch, beta coming up any moment, is sucking in all resources, so addressing the AC@H issue for MAC wont be happening until after the new project launch, so please be patient.

thanks
