FWIW, I received my NWA match today. Only got Gold (matching to my AA EXP status) and only for the 2009 program year, but that's fine. They also offered an "Elite Challenge Hopeful Promotion" to get Platinum if I fly 7 RTs in 90 days (which I won't be doing).

Not sure if they just finally responded to my fax or if my email got them to act quicker.
