In order to decrease the distribution of serial keys over ‘bad’ hacking sites, I would like to present a feature that probably will be released in SKGL 2.1.1.0 – Machine code locking. This means that each serial key will have support for machine code storage, so that the serial key is bounded to a single computer. As you know, the project is open source, and you can join it whenever you want to (http://skgl.codeplex.com/). If you think I should change something, please write to me or comment this post. Good Luck!
