PyGrunn community site

Yesterday at the Monthly PyGrunn meeting we decided to make www.pygrunn.nl the central hub for all things PyGrunn. The question is how to turn this site into a real community site. Currently PyGrunners are sharing using a mailinglist, LinkedIn, twitter, pygrunn.nl, Google+ and facebook. Let's start the discussion: What kind of site should we create for the PyGrunn community? A few requirements: - Everybody should be able to contribute to the site; - It should be simple to schedule events (Monthly PyGrunn for instance) to which community members can sign up; - It should be easy to connect posts to social media; - ... The current site is built on top of AppEngine and Django, but there are also Facebook and G+ pages.
