Dear All,
I have now produced versions of my Collapsed Topics course format that will work with Moodle 1.8 and 2.0 - please use the links in the database entry - http://moodle.org/mod/data/view.php?d=13&rid=2307 - or on its page in Moodle docs -> http://docs.moodle.org/en/Collapsed_Topics_course_format
The latest 1.8 version will be built this evening, so please hold off until Thursday.
Cheers,
Gareth
