Hi, What site, in your opinion, could be developed on 4 letter domains that really don't mean anything that obvious.
You could see what those 4 letter acronyms could stand for & develop something along those lines. Or, you could always make it into a proxy site
easy to remember and to type. plus they are all registered so the only way to get one is on the aftermarket. price of the 4 letter domain depends on the letter quality and combination of Consonants and Vowels.
