write-protecting a wiki

[lleighh2]

I think wikis are a good starter CMS for newbies. I like that they are lightweight and the user can enter text without knowing any code.

I've been experimenting wih tiddlywiki. Is there a way to write-protect certain fields/pages? So that the user can only enter in certain spots, leaving the original text untouched?

If not can this even be done with any other wiki?

Generally speaking, the 'user content' area is a free for all. Editing rights are often implemented but they only control whether or not a user may edit, not which part of a page they may change.
