are there any public wikis that allow password protected contents?

Question

I want to migrate a local wikis contents to a public site but I don't want to install a wiki. Are there any wikis that will let users create a password protected sub-content area?

Answer 1

Sounds like you're looking for a Wiki farm

Answer 2

They don't use a special wiki syntax, but as far as function is concerned, Google Sites, are wikis, and they can be password protected. You would probably need a Google account per content area, but they could all be linked from a public page. And they are free.
