Yes, I bought my own domain under the name Postagulous. Basically, I went to a random word generator and put in the first four letters Post and found out what it would come up with. I think the 16th or so suggestion was Postagulous.
Not only that, but after experimenting with Blogger, and I still don't know why it's working correctly now, I'm using that to do the Postagulous thing. I was having trouble getting it to work with my bellsouth account, which is where Postagulous actually is located at. I just bought the domain name from godaddy for $23 for three years.
