@fulv and I worked together to hand off Foundation sponsorships management to him. There is a sponsors database on plone.org (custom content type, custom workflow, yessss!). Currently we list sponsors on plone.org but providers (and sponsors) on plone.com. The plan is to begin displaying providers on plone.org and to move plone.com content back to a new section of plone.org. We have started the code for the new plone.org/providers listing and are testing it. This will vastly simplify the process of adding/updating/removing providers, especially since plone.com was turned into a static HTML site over a year ago.
