At noon today (Eastern Standard Time), the long dead ORDB spam identification system began returning false positives as a way to get sleeping users to remove the ORDB query from their spam filters. The net effect: all mail is blocked on servers still configured to use the ORDB service, which was taken out of commission in December of 2006. So if you're not getting any mail, check your spam filter configuration!
No telling how old the Dax site is.
I have called DAX, got his answering machine. He returned my calls promptly. I was asking questions about his 4 stroke engine for my worksman trike. I told him about Staton-INC.com. and the engine & kit I could get from them. He pulled up the site while I was talking to him. He was very complimentary of their engine/kit an recommended that I buy from them (Staton) since they had everything I needed. I would definitely buy the Titan 2 stroke from DAX if and when I decide to purchase a 2 stroke. He was very nice and willing to help. He has responded to my emails promptly in the past. I have no personal interest in this company. He just seems like a good guy to work with.
