Choose a clear title, not excessively long, and insert it by simply writing in the designated field, at the beginning of the event creation process.
The title is one of the mandatory elements for being able to save your event page.
If you want, you can also add a subtitle to your event, using the designated field on the event creation page. In this case too, just click and write.
