Re: Subcategories? (mainly file gallery)
Hi tckepley, and welcome to Tikiwiki Community
Interesting thread... A shame that full LauLima code is not free software.... (the same on a nice menu engine I saw, but closed source again... )
If you want to keep track on free software tools integrated within Tiki, you have to check the Workspaces feature that come along in Mod Aulawiki: they were coded from scratch for Tikiwiki..., and are being used for production on some research projects at University of Barcelona (Spain; closed environment to keep privacy of our students), as well as on a non-profit cooperative offering courses on free software in Barcelona... (http://moviments.net/cursos)
You can test aulawiki and workspaces on http://edu.tikiwiki.org
