Thanks a lot to everyone who offered to help.

The selected people should have an active beta registration by now. I'm really looking forward for your feedback. Feel free to use the Beta forums (I will notice your names) or send me a PM in here if you like.
Thanks again and I will let you know when we are ready for more testers. Sorry that I can't invite all of you right now. I'll try to add some more with one of the next waves.
