You are wrong. Provided that the license is GPL, LGPL or BSA based, then no permission is needed.I'm amazed that *source*forge allowed you to host this.Please, shoot me down if I am wrong - I am no expert on Open Source licensing, but attribution is NOT optional.
Please give the guy a break. I admire him for wanting to contribute to the open source community, and wanting to get involved.
David, keep up the good work! I'm thrilled that your starting this project :)
