Topics and user permissions - please help!
I'm trying to find a CMS solution which will fit my needs for user permissions, and it's much more difficult than I thought. Tiki looked like it would fit the bill, but I can't work out how to get what I want, which is this:
My site is divided into a number of sections (imagine a "lifestyle" site with sections on Gardening, Cooking, Plumbing...).
Each section has a group of "experts" (in cookery, gardening, plumbing...) associated with it.
I want ALL users - including anonymous - to be able to SEE all the sections.
But each group of experts should only be allowed to UPDATE its own section.
I thought Topics/Articles would allow me to do this, but I cannot see any way to apply any permission other than read/not read to a Topic. I don't want to use the Wiki because it's not collaborative in that way - each article should be a standalone and independent article, not designed to be modified.
I've read the doc and done a test install - but it just won't do what I want. Any ideas, PLEASE?!
Thanks very much - JoelG
