[Pmwiki-users] Visitor Comments

[Nils Knappmeier]

A friend asked if this was possible with a wiki:

He wants visitors of his website to be able to write comments to the 
stuff that is on there. Yet, not everybody
should be able to just change everything on the site.
To be concrete, there would be a form on every page and text entered 
into the form is added to the end of the page. There might
be a password to edit the page but no password to enter a comment.

Is something like that possible with PmWiki?
