Akabeko relocating or closing; not sure which

Dreamhost sent me a letter this week telling me that come December I can no longer use the sekihara.dreamhost.com subdomain. 

Phooey.

I can register a new domain, or switch to a different subdomain on dreamhosters.com, or just let the site die.  Strangely, even if the site dies my email will persist, so whatever I do I don't have to worry about changing that.

I have no idea what (I want) to do.  =/

ETA:  I can't get sekihara.com or sekihara.net...
