To answer the first question. No I have not emailed GD about it. I really like the GD response time and the fact that English seems to be the first language of all of their employees. However, I have been getting a lot of wrong answers from them recently. Answers that I know are not true, but maybe they just don't want to deal with the question, so they answer it with the most likely answer and don't really pay any attention.
The names that this happen to me on normally, happen not long after I own them. As I mentioned in the first post, I was actually thinking that they had not changed over in the first place. Because of the daily eanrings of this name, I know exactly how long I had it. I bought it from TDNam. Had it in my GD account for 1 full day before moving it to Sedo and got 1 day of stats at GD CashParking. Then moved it to Sedo for approx. 3 days and got stats there each day. Then it started to get stats at GD Cashparking again. It spent the last 2-3 days there, before I realized and changed it back to Sedo.
The nameservers at GD should say CPNS01.SECURESERVER.NET and CPNS02.SECURESERVER.NET (They have different nameservers for default hosting than for parking). The biggest problem is that GD does not tell you where the nameservers are when you look at the list of names in manage names. You actually have to click on each name indiviually. I get around this with GD Cashparking (It is free with my Discount Domain Club, I would not pay them for it). I check the Cashparking account every so often, and see what names are getting visitors from the last few days, if any. The ones that do, I know either the nameservers did not change or have changed back to GD. I do have 2 names that I leave at GD intentionally, everything else I try to move.
