Tiny URL question...

[Aletheia]

Hi all-
does anyone know how "stable" tiny URL's are? I'm not sure if stable is the right word... I'd like to be able to count on a tiny url as a website name for a bridal shower... which means what gets printed in the invites needs to be correct when the guests finally get around to looking at the website. Does anyone know about this?

I'm almost positive they don't expire.

I'm pretty sure I read that too when I first checked out the website - that the tiny URL links never expire.
