I've rejigged the categories a bit, just moving the course category down now that the main function of this site is a general forum. I feel that we're missing a category or two though.. We've got announcements, Q+A, installation help, resources and innards.. How about a 'sharing' category? Moving 'installation help' under 'q+a'? A category for talking about process / music?
Also a most discourse-based sites don't have categories on the front page but just all the latest threads, e.g.:
Should we move to that model?
