Hi, Dokrockr,
I kinda like the name ... it has a nice ring to it and it certainly mirrors the "pending delete", "expired", etc., notions that are so popular in searching for names. The only TINY drawback that I see is that the meaning of the name is a bit ambiguous. Is an expiresnow.com site expired right now, or will it be in the next few seconds, or what?
As I said, that's a very TINY drawback. I think that you should be able to do quite well with this.
Good luck to you!
Sheila
