How would you describe an eventual brandability option with this name if you know any? Besides, the letters in the name might turn confusing when written in lowercase I think. Is that a double "L" or an "L" and an "I"?
LL.tc or LI.tc or are you saying 2 letter .tc domain? If you got 2 letter domain at reasonable price, just grab it as it would be an asset in next few years.
oh, I meant to type LL.TC (letter,letter.TC). I'm going to use it for a free sub-domain site so people can get xxxxxxxxxxxx.LL.TC.
