Git
Local Git
I have a local git repository where I am dabbling with things, you can either use the web interface at http://git.andreasbaumann.cc or you can checkout read-only copies with:
git clone git://git.andreasbaumann.cc/repo.git
If you have comments or patches, you can send them via email.
If you want to collaborate, I can give you write access.
Github
Forked projects are on Github.
