I'm new to this Open Source things...
1.) I made the program, then someone came at get my program, and RENAMED the name of my program, and redistribute it saying that its HIS work. Do I have any protection from these?
2.) What are these licenses (like the GPL)? What's the difference between giving the program with the source code, and saying, "Hey! I got a program for all of you guys, you change, edit, or do whatever you want", and the difference between having a license?
3.) What do I need to do to obtain a license? (like GPL)
