I just sent them an email, I looked it up and there was the same problem at another domain forum, seems nora from sedo answered the problem with
"Please use: http://www.sedoparking.com/domain.com (where “domain.com” is replaced by your domain name)
As already explained to you - if such forwards are banned in your country of residence, as is the case here, I'm afraid that you cannot park the domain with Sedo "
but my name was working fine until now, im in New York, US so it should work fine.
