Sign up for the workshop under your own name. Make a note during the registration process who the workshop is for (name, email address) and tell us the date until when we should keep this under wraps.
You will receive a confirmation email with further information.
There is no step 3.
Don't worry if you're not sure if the workshop is the right one. I'm happy to talk with you to find out which one is a good fit, and if it turns out that it doesn't work, there's always the possibility to switch to a different one.
