To access the free tutorials you will need the password (I really wanted to go with a secret handshake, but you can see how that might be a problem in the webisphere).
If you are already a museletter subscriber, you will have received the password in the April 2014 Studio Newsletter – if you’ve subscribed after April 2014, you can find the password in your welcome email (which will arrive after you’ve confirmed your subscription).
Don’t have the password? It’s easy to get! Simply find the “subscribe” button at the bottom left of this webpage, fill in the fields and submit, click “confirm” in the confirmation email, and in the next hour or so you’ll receive a welcome message with the password.
