website and email might be down for a few hours the next days

Our website might not be reachable for a few hours within the next days. Also emails could be delayed for some hours. The reason is that we are moving to a new server. So just try again a couple of hours later when something doesn't work. There also might be some strange effects caused by the migration which could take some time till they are fixed. So please only write us about severe problems at the moment (in about 2 weeks you can write again about cosmetic ones again ;-)
