I really don't believe that it is a health issue. The reason I can say that, is because he has logged here since 6-17, and was online on 7-3 and 7-10 but he will not return any emails, IM's or even phone calls.
He was logging in the whole month of June and even part of July, if it was a health issue, and he could manage to log in and even post since 6-17, why would he not even try to contact me or anyone else.
Hell, if he can post on AR-15.com, he could have posted a message saying that he needed to talk to you or me.
I wish I could help you, but I am in the same boat with you, and at this point I am filing a case of mail fraud against his wife (who received my Postal MO).
