Hello , thanks once again for help Biggie , as far i know in IDN world this is one letter domain but i may not renew this one , you can check flippa auction , every idn punny code is more than one letter so there may be no idn with 1 letter punny code.
If the puny code was a single letter then it would just be a single letter .com. Whatever that puny code would be, would also be a domain name. The real domain name is the puny code, but it is like a "short code" for a second domain name.
BTW, its always a good idea to add a domain name to your account rather than pointing it to the parking company and not adding it. It appears you never added it to your Sedo account. If you DID get traffic you would have only made money for Sedo, not for yourself.
