Right now there is only a simple list of 3rd-party Mezzanine modules in README.rst, but I think it would be better to have an official Mezzanine modules comparison grid on http://www.djangopackages.com/. This way more data could be added, new modules added by authors itself and non-Mezzanine users would find them more easily.
Django CMS has this http://www.djangopackages.com/grids/g/django-cms/ and they are even using their API to put the extension list into their page http://www.django-cms.org/en/extensions/.
I set this up a while ago here:
It's just not very visible. Perhaps if we ask @pydanny nicely he can add it to the grids in the header of the site :-)
Thanks so much!
@gw0 what we'll also do is feature a link to the grid from the docs, and possibly create a page on the project site that lists all the packages. I'll reopen the issue for now.
Moved this to the repo for the project site.
