The SW Combine Administration has declined your membership application providing
the following reason :
Your e-mail address was not accepted because it appears to be from a private
domain. We require private domains to use admin@ or webmaster@ as proof of
ownership and to prevent more than one account from that domain being signed up.
I have one E-Mail address in my own domain, I won't buy another E-Mail address just to play a game.
Checking WHOIS on my domain clearly identify myself as unique owner.
It is proof showing that you are the owner, for a domain owner does not give out the webmaster@ or admin@ or info@ to a friend or strange for that matter.
Where as someone with there own domain can create multiply addresses for friends, technically making the addresses free.
Yes it is possible to have a domain where you only pay for the one address (a pop address that is) But it should be possible to make forwarding addresses that goto the same address. Most domains have these at unlimited.
