You were invited to someone's team
The promoter sends you a link. Open it on your phone. If you have the shabanga app it opens there; if not, the page shows Open in the app, and on an iPhone a button to get the app. Installing the app on its own does not bring the invitation across, so after you install it, come back to the link and press Open in the app again.
The invitation names the promoter and the night, and lists what you will be able to do.
New to shabanga? Enter your email, choose a password of at least 8 characters, and press Join the team.
Already have an account? Press Already have a shabanga account? Sign in, enter your usual password, and press Sign in & join.
Either way you land on My Events, with the night there.
If the promoter added you as someone who already has an account, there is no link at all. You get an email saying you have been added, and you sign in as usual.
If the link says This invitation has expired, ask whoever added you to send a new one. Links last a week, and each one works once.
