If you can't find you choir on our list while register for the festival, go ahead as described below:

After your "personal registration" you will be asked for your membership to a choir. 

First you type your choir name in the field to check if it is already on our list. If not you have to generate "your choir" in the registration menu. You can find there a button named "+add chorus, ensemble or festival chorus". If you finished this you will be automatically an administrator of this choir with the special right to register this choir for the festival and also to add others as choir administrators (but, first they have to create their own account and add themself as a member of your choir). We recommand to have at least two administrators for each choir.
