I'm selling the five-letter domain name seixi.com
Obviously I'm not expecting to get $13 million like sex.com did, but the connotation is there, and you can pronounce it like "sexy" if you like. Good five-letter dot-com names are getting hard to find. This was registered in 2008. It has never had any content, so it has no pagerank or traffic.
Reserve price is 100 BTC. Sold to the highest bid by Friday 21 January, noon GMT. I might sell it privately before then if I receive a substantial "buy it now" offer by PM.
