BTW, just FYI, the chances in you snapping up a domain after it expires are next to zero...

There are a slew of companies around who snap up domains (regardless of the quality of them) AS SOON as they expire in the hopes they can either

a) resell them to a person (such as yourself) who has an interest in them for their name value
b) sell them back to the previous owner who simply forgot to renew in time
c) sell them to a webmaster who is interested in the traffic the domain receives
