[CentOS-devel] Pull request/Changes to CentOS Extras repo??

Hi guys... 

I have some packages in the Extras repo, that I would like to be built for python3 as well as python2... 

I can provide the changes for the spec files, but what is the official way to commit changes / pull requests???? 

I would of cource then become the package manager of these packages... (we need them in the COPR project)

Regards

Martin Juhl
