My wiki at
noting-wrong-here.wikispaces.com
has a series of 4 lesson on setting up a wiki. It was orignally
setup for a series of workshops I taught for the LPVEC staff. I use
wikispaces, but there are several other wiki platforms teachers
use. These include
PBWiki,
Tikiwiki,
Wikimedia, and
pmwiki.
Not sure what a wiki is or how they work. Watch the wiki video,
look on the Videos page.
