Hello, Kei! Would you like to have commit access to the guix git repo? so that you can push the patches yourself (after they are reviewed). For this, you need to create an account on <https://savannah.gnu.org>. Then one of the project admins (probably Ludovic) can add you to <https://savannah.gnu.org/projects/guix/>.
Make sure to read HACKING file in the guix repo, and if anything is not clear, please ask. -- Alex
