I've got a bunch of domains that I am holding onto and probably won't let expire until I find a use for personally or find someone else that has a use and wants to buy. I'm not going to list all of my domains here, just some of my favorites which I have stumbled up over the years.

earthwebsky.com - This is BA
macaronies.com - Definately catchy, if you don't want people to forget your domain
processingdept.com - Very corporate
shell32.com - If you're looking to build a Microsoft Windows resource site
useplugin.com - Good for a software/shareware site
developercentre.com - I can see putting something together here, but how many sites do I need?

Feel free to post any offers.
