Roberto,
Was this what you had in mind? https://openacs.org/projects/openacs/packages/
I also set one up for dotLRN https://openacs.org/projects/dotlrn/dotlrn-enhancments/
My thought was to use ETP so that people actively working on a package had edit rights on the page and could maintain that page themselves.
We still need someone or more likely a bunch of us to maintain setting up new subsections, granting permissions, reminding people, putting in links to forum threads etc.
What do other people think? Is this a good way to proceed? If you are working on a extending/creating new functionality would you be willing to summarize and update your plans/progress using this system?
