For in case things went wrong with the new server we used 2 names, mastermoves.eu and mastermove.eu. mastermoves.eu forwards you to mastermove.eu. But now mastermoves.eu seems to be unreachable sometimes, so use mastermove.eu in that case.
Why dont you let mastermoveS.eu forward to mastermove.eu? MastermoveS is the name of the site and the name displayed on all your games.
It will be mastermoves.eu only (or with mastermove.eu forwarding to mastermoves.eu, in case of a typo), but better look at forumtopic #616 about this issue.
