Thanks a lot to all of you who have found out something or shared insights & thought.
Yes, a company that has mail forwarding set up for the address they post as their business address on their web page would be regarded highly suspicious in Europe.
And, as Nagle has found out, if someone was to send a letter to their postal address, it would never arrive, which is definitely another suspicious thing to a European.
Also, I have sent Tradehill an email a few days ago at '
support@tradehill.com' - and now I have received a message saying that the email did not get through ...
Sorry for not posting more often in this thread (in fact, in the whole forum): my problem it that I am able to post only once a day.
Otherwise I get the error message "The last posting from your IP was less than 360 seconds ago".
Or I get an error message saying that I have sent the post already (which is, of course, not true).
