Moodle+Wikis

Moodle Feature - Wikis
Wikis are editable web pages. There are several types of wiki available in Moodle, allowing pages to be seen and edited by everyone, some people or just the user and teacher.

Using a standard text editor within Moodle you can add words and pictures and even create multiple pages linked together.

Wikis are great for collaborative projects spread over time and logging of changes makes it easy for the teacher to see who has added what.
