Please let me know if you continue to have problems.
This is OT, but I emailed you privately 5 days ago asking for a teacher's enrolment key regarding your sl-lists.net site, but never got a reply. Did you receive my message?
Could you also post the most up-to-date version of the module on the modules page? The one which is there is dated May 10.
Looking forward to seeing you in a couple of days
No... this bug is 4 years old and doesn't affect Moodle 1.8...
Is some thing not working the way you think it should?
