For those who are just now joining this thread already in progress... I recently learned how easy it is to disassemble .NET programs. I belived my source code was being posted without my consent and have since been in contact with the user in question and all is good...
That said, please, if you're a .NET developer who's considering creating and selling a commercial program there are programs out there like .NET Reflector (FREE) which can easily disassemble and display your code in seconds.... Do yourself a favor and look into obfuscation software for .NET which will atleast make it harder to disassemble and will, for the most part, stop the casual hacker from viewing your code.
I appreciate all of the positive feedback I've gotten from everyone here and I'm moving forward with the GCS program...in .NET. I am going to release it as open source but I'd like to get more of the development out of the way before I start getting other people involved. I haven't had much success with multi-developer situations and I'd like to get my "big ideas" done before letting everyone else have at it.
