This, by any means, is rather a breeding place for communities rather than a fully developed community. Consult the Main Page for the Portals to be found in this Wikia.
Or visit the Meeting Point if you want to help create some mapping here.
Proposals can be found in the category category:proposal.
There is a category:essay for essays.

Proposals and policies for software recensions go here: Education:Software recension.
Semantic Wiki Edit
Thanks to Wikia support we have Semantic MediaWiki available now (see Special:Version). I like to ask everybody to consider possible uses for the extension. I think we should draft a plan before making use of it, otherwise the result may be inferior. See Special:Properties for properties in use and Category:Special property for built-in properties of Semantic MediaWiki.
