I'm looking to fork a project on GitHub that was last updated "Three Years Ago" according to GitHub, I've written to the author and not gotten a response - so I assume the project is dead.
I like the project and what it stands for, I use it every day in fact, so I'd like to continue a version of it, at least. The project has been licensed under GPLv2, is it possible for me to upgrade my forked version to GPLv3? I'm new to open-source licensing - usually I just write plugins under the MIT license.
Any advice you might have would be appreciated - this will be my first project of any kind, let alone an open-source one.
