Vlk,
When I first read this thread and saw your post asking for advice concerning your testers, I was thinking:
1) Beat them serverely about the head and shoulders then take them out for a beer.
2) Skip the beating, take them out for a beer, then make them pay for it.
But, upon seeing the subsequent post about problems with Hearts, I have to recommend option one.
All kidding aside, kudos to the entire Alwil team for produding a great product. Thanx!
