We use conflucence for meeting notes, daily student assignement tasks lists, etc.

I end up copying a page text, to a new page, and saving it.

Other users were suggesting using the move feature, and then creating a new page with the same name.

It would be nice say, save this version of this page (add date to the page name), and lock the page. Basically, make a historic note of what the page said.

It might even be that these entries would be blogs, so that the blog features could be used.
