No. If you are an organizer we recommend you create a Pelago account using an email address, not through Facebook. When it comes to ticket scanning on the day you may want to share your Pelago account with others helping with yout ticket scanning. If you are signed up on on Pelago via Facebook it won't be possible to share your account.
But don't worry, if you have already signed up via Facebook and want to switch your account to an email account, just get in touch at firstname.lastname@example.org and we will make the switch for you!
