Expirator would be great to have.

It would be neat if you had options for how to link is expired:

1. Number of days
2. Date

In fact, it could even be interesting if you could make a link valid only during certain periods. For example, you might have a link owner who wants their link to display only during Valentine's Day, or whatever. This would sort of be a Super Expirator, I guess.

Thanks!
