Hello John. I did some searching online and found an old answer on StackOverflow about creating multiple mercurial repositories for a project: https://stackoverflow.com/questions/17307189/how-do-i-set-up-a-second-mercurial-respository-on-sourceforge

There is also another answer about multiple git repositories: https://stackoverflow.com/questions/64921561/how-to-create-multiple-git-repositories-in-one-sourceforge-project

Both answers indicate that there are errors in the SourceForge documentation.

Hope this helps.
