Hi if I am not mistaken to contribute to this bug one should look here: https://www.debian.org/devel/website/using_git
I noticed that you advise to log into salsa and request write access to the repository https://salsa.debian.org/webmaster-team/webwml To lower the bar for newcomers, you could suggest as first step to work with Merge Requests. So the new contributor johanna would log into salsa, fork the webmaster-team/webwml repo as johanna-guest/webwml, make changes and file MRs. This would make it easier to allow anybody to contribute immediately, without the need to screen them in advance. Paolo
