On a very off topic, how much do you have to pay for a four letter domain like yours and whats the process like. Did you use something like sedo/godaddy? I've always wondered how difficult is it to acquire one.
In searching, we also found this seller on ebay (no affiliation) that had a bunch pretty cheaply. I sort of liked omot.com, but not enough to buy. http://stores.ebay.com/Short-Domains/LLLL-com-4-Letter-dot-c...
