Producers, DJs, Promoters, Venues and Artists - add yourself as an entity. From there, if you view your entity, you can add images, links, contacts, and link yourself to events.
Add a series under the events menu for reoccurring events.
For one offs, or instances of a series, add individual events.
To import (some) event data from facebook, click Add Event to open a form, and copy the event's FB URL into the Primary Link input, and click Import. It will add the name, slug, short description, venue and anything else it can scrape. Proceed as usual.
Any event that has been added will appear on the calendar automatically in blue. For each series, the next instance that has not yet been added will be displayed on the calendar in light blue.
