If you already have installed and opened the Clubbable app you probably noticed that your got asked a few questions the first time you started the app about how you got to hear about us. Among the options there is on button that says "I have a code". This is primarily used for 4 purposes:
A friend of yours thought you would also like the app. Using his or her code will add you as a friend in the so you can easily be added to party groups.
Your friend already created a party group and send you an invite. Using that code will automatically put you in the party group and add you as a friend.
When we recruit promoters we give them a special code which gives them promoter access straight away without having to apply for it in the app.
