You can click the Preview button at the bottom of the Add Event form to see a preview of the detail page for a new event. You can update the event information and preview the results as often as needed prior to saving the event. For more information, go to http://www.trumba.com/help/event.aspx
With the "Automatically invite from wait list when space is available" option, you automatically invite (and reserve spaces for) people on the wait list when one or more spaces opens up. By adding a response timeout, you continue to invite the next person who joined the waitlist (automatically) if the previous invitee doesn't respond within a time limit that you set. With response timeout, it's first come, first serve amongst all the people invited, which makes this a great option to use to help fill the available spaces for your events. For more information, go to Manage the wait list.
You can apply robot detection to event submission forms in Trumba. With robot detection enabled, event submitters must pass a CAPTCHA to attest that they are human, before they can submit an event. (A CAPTCHA is a program that presents a test designed to protect websites from non-human input, or “bots.”) For more information, go to Set Up an Event Submission Form.
