You'd be the first if you're playing in Europe region
That said, you need to know that the regional servers are not linked and characters should not be existing across multiple servers.

XFireNeo is your Battletag?
It is missing the # numbers if it is.

Good idea but have not had anyone plan to set one up yet.
I was planning to use the free Vent of Diablo Expressions before.

You can choose to play in any of the regions.
But RMAH will be limited to whatever address you put in your BNet acc.

1. What address did you put in the BNet acc?
2. Check your BNet account for your full Battletag (it should be something like YourNick#4digit-number)

unless UK connects to US server too, you are on our own buddy~
