The Squeakland Site. Squeak is being used increasingly in educational applications. This site is dedicated to that use. This is where you can download the Squeak plugin that lets you execute Squeak from within the browser.
If you want to use Swikis or PWS in your classes (or class projects), there are two places to look for information. The Swiki Swiki has the latest Swiki based on the Comanche web-server. The original PWS Swiki Swiki is still available and contains information on PWS and variations of the PWS Swiki.
