Hi Nik!
Thanx for your email. I just tried to email you back but once again the email came back with the following error. Maybe there's something wrong with your server?
Best, Marco

Well, I use the same ISP as Nik and I know there have been problems receiving e-mails from Germany. I don't know why this is, but I know of at least 3 different persons from Germany who have tried to mailed me, and failed...some German mails do come through though, strangely enough...
