When you sign up for a self-guided course, you will receive an email with login details and a link to Moodle. You can then simply click on the link and it will redirect you to Moodle. 

In case there is a problem with accessing the link through the web store, you can access Moodle directly at moodle.bslfirst.com, enter your username and password to log in and you will see your course.
