I will say this in regards to post 667 I did message the authors of the posts to contact one of gw customer support people on skype (gave the persons skype contact to them).
I don't think they have, but the option is there.
Cryptonomos is also the escrow provider, not the giga-watt team which is most likely why they only answer the easy questions.
I've said a couple of times, message giga-watts support they're pretty quick on the reply side.
