I'm thinking to point the project page to the source repository (e.g. GitLab) when the project has sources, but doesn't have a project page.
That is a really good idea.
As for the projects which never spawned code, I'm wondering: should we simply remove those off the system (after contacting the project members, of course)? I mean, there's little Common Lisp value in them...
Definitely. They make the projects hub list frustrating to browse.
