Some time ago I developed a [small project][1] for use in unit testing scenario's and published it on Codeplex. Back then [I choose the GPL license][2] but I didn't really understand it. Today [I changed it to MIT][3], because it's a much simpler license that I can understand. 

I like to be recognized as the copyright holder, but I want everybody to be able to use the library without worrying about license issues. I think MIT covers both, but not 100% sure. '*Virality*' is not an issue for this project.

Would this license (MIT) in any way prevent a person to use my library for the unit testing of a closed-source commercial or private project? In this regard, is my recent change to MIT a change for the better?
