Hi! For full access to courses you'll need to take a minute to create a new account for yourself on this web site.
Each of the individual courses may also have a one-time "enrollment key", which you won't need until later.
Here are the steps:
Fill out the New Account form with your details.
An email will be immediately sent to your email address.
Read your email, and click on the web link it contains.
To reset your password, submit your username or your email address below. If we can find you in the database, an email will be sent to your email address, with instructions how to get access again.
