Alan,
Thank you very much for that - it's terrific for me to hear stories of Moodle being used out there. Particularly such positive ones!
PHP programming can be great fun as you sometimes get a lot of effect for a little effort (then again sometimes you get little effect for a lot of effort) ... sounds like you have some budding hackers there (not crackers, hopefully).
I'm very interested to hear more about how you have used the journals ... did you use few or many? When I designed it I was planning for each journal entry to be quite short, and that teachers would set up one or two journal activities in every week. Since then I've found many people are using only one or two of them in a whole course, and encouraging repeat visits so that they build up one big entry over a long time. As a result I'm thinking of new ideas for the journal to make it more dialogical, like a private forum between student and teacher.
Glad you like the quiz module ... it was my most frequent request and I put a lot of work into it. Since it's now released mostly all I've heard is requests for new things instead.
One more thing - are you using the LDAP authentication?
Cheers,
Martin
