Would it be easier to just edit your name in your profile and make it the name that you use now? Does that not update the name shown in the top contributors page?
I know that contact information can be pulled from repository data. (I’ll manage it later when I have time).
What makes me uncomfortable now, is that information being in plain sight to every visitor.
What I tried doing now, was modifying templates/repo/latest_commit.tmpl. Saved it into $GITEA_CUSTOM/templates/custom/repo/latest_commit.tmpl (namely GITEA_CUSTOM=/var/lib/gitea/custom but I do not remember setting it). Restarted multiple times, both in prod and dev environment.
