Guild Wars 2

Can anyone from the EU mail Americans with out the trading post going down and not being able to send mail? Cause me and my friend had to swap sever and we just lost the ability to do anything when me messaged our american guild members items.

I have no problem mailing / sending goods to people on EU servers from US one. One friend & I trade small items and exchange mail regularly without any side effects.

(However, we are annoyed that we cannot actually play together, as we expected from beta testing.)
