Hi Maria,
Welcome to the course. I'm glad you're interested in helping your students get familiar with Moodle. What is your background with Moodle? Please re-read the instructions and answer the questions.
In case you're having problems with Colossyan to introduce yourself on your phone, please use HeyGen instead.
I'm looking forward to supporting you as you develop your own Moodle course.
Warm wishes,
Nellie
