FabMo is currently using this online scheduling service. If this is your first time scheduling yourself in this way, when it asks you to "login" you will need to "create a new user account" and create a password for this scheduling application. You will get immediate email to verify the email address. Click on the link therein to complete the verification process.
The fact that you get FabMo newsletters does NOT automatically mean you are registered here. There is no password associated with any other FabMo function.
