I am thankful to all of you who tried to find 4L,5N,6N.com domains for me.I feel sorry that unfortunately we didn't find any result.To show my appreciation and considering your efforts,I have decided to make it easy for you guys.
Since we didn't find any 4L.com,I suggest you guys find me some 5L.com, but only if they are good with repeating letters for example only composed of two different letters hhccc.com etc and doesn't include vowels  O I U E A V.I will pay 0.02 btc per available domain but domain should not be a premium one
