All of my games are available to everyone for free.
However, if you enjoyed any of my games, a couple of bucks to cover website hosting costs and support my ongoing efforts would be gratefully appreciated. I think $2 per game enjoyed is a fair price. Thanks.

Yeah, the notification system works pretty well - it's just the 'notification' module for Drupal, doesn't take a lot of effort to set up.
The games and utilities on your site look interesting testaware, I'll have a go at them later.
I have some further things to say about programming - mainly I've had another change of heart and I'm playing with C++ again - will do a new post soon.
