Can I create a new project based on an abandoned one licenced under GNU GPL v2?

Question

I've found a SourceForge project with a solid core that I would like to improve. The project hasn't been updated since 2007 so I assume it is "dead". I sent an e-mail asking to become a contributor to the listed project manager last week but still haven't received a response. The project is licensed under the GNU GPL v2. I would like to contribute to the current project but that doesn't appear to be possible.

Can I modify the current source version of the project and release this modified project? I would keep the same license on the modified project.

Answer 1

yes this is the whole point of the GPL, take it, improve it share it.

Answer 2

Yes, you can even change licenses to GPLv3 if you want...

Answer 3

Yes, the GPL V2.0 is still very much in effect, and still holds value. You can still take, modify, use as you wish, with the main caveat that you share your source code derived from the GPL'd source with others.

As per the GPL V3.0, when your release your source, you can license your work under the GPL V3.0. You can convert 2.0 to 3.0 with new releases but not backwards from 3->2. Whether the existing work's license is converted is entirely up to the current author.
