Re: what is the best way of setting up access permissions
Best way: use workspaces, from AulaWiki Mod (0.7+ from http://www.escire.com/aulawiki/mods, which is MUCH newer and improved than "1.2" from mods.tw.o)
Documentation on http://edu.tikiwiki.org
(as there again, Peter, if needed, on edu.tw.o users forum)
And welcome there 
(sorry for taking so long to get and answer your message)
