Sorry, Swiki is another implementation of Wiki, I am just a demanding user of eWiki and give my comments to M&M. So my comment here is that I think teachers should have always access, because we are an educational setting not a wiki community.
I use Swiki as a stand-alone program until this eWiki is fully integrated in Moodle. I like this integrated eWiki now very much: And I prefer the HTML-editor above the Wiki-simple-text-philosophy..
But this Swiki option (coomentbox) was very nice: the only thing a user had to do was place a commentbox symbol on the page, place his email in a "send me an email"" -field and lock the page. (Students can take ownership of a page when they put a lock on a individual page of a group-wiki.) A visitor sees then the locked page with the commentbox. As soon as the visitor types his comment and presses the comment-button under that box, the owner gets an email.There is no database behind it, pages are stored in XML-format.
Another option I did like was the possibility for a webuser with editor rights to create a webform instead of the standard fill-in screen. The page-storing mechanism makes collecting the content of the forms to difficult, no database..
Swiki is a standalone server that runs on Mac, Unix, Windows.. We used it for several years at our secondary schools to collect experience with collab-work on a website.
The program Swiki is written in the Smalltalk version Squeak.
The pioneer Alan Kay is one of the founders. Their children project eToys is inspiring
During meetings they play the game to install and run this Swiki-server in less then ... seconds.
