The original Moodle Tool Guide was developed by Joyce Seitzinger. We (Sherry, Dave and myself) redeveloped it as a Moodle Lesson (which will be available here soon). But I also felt that it should be available in HTML form to make it more accessible.
At the moment, it’s hosted in my dropbox so I can make changes easily. Eventually, I hope to have it hosted somewhere and downloadable in many formats.
