Is there a domain reminder service?
 

There are some domains that I want to buy that are already registered, but they are going to expire in the next 2 to 4 months. Is there any site that will send me an email reminder if they expire?

register.com automatically reminds you and automatically renews your domains... they also automatically refund your charge if you dont want a domain renewed.

their xfer services suck.. but they are a solid company.
foreman interactive will be around for some time.

Snapnames will notify you everytime there is a change if you purchase a back-order on a name. They will notify you once a week if there was a change, if you use the monitor service instead.

snapnames is great
