I was invited. How do I sign in the first time?

Your invite email carries a temporary password. Sign in with it once, in the app or on the dashboard, and you are asked to set a password of your own. That is the whole of it; there is no sign-up form, because accounts are opened by hand.

Your email address is the username.

Why there is no sign-up: we open accounts a few promoters at a time so that every one of them can reach a person on a show night. If you were not invited and want in, apply.
