Hi Abby,
Thanks for checking out our plugins!
There is not any built-in functionality for users to indicate that they are interested in an event without registering. It looks like you may have tried to link to another post that was related to this topic, but if so, the link unfortunately did not come through.
RSVPs only come with two statuses – “Going” and “Not going”. If you go with Event Tickets Plus (even if you are only working with free tickets), then you will have options for when to generate attendee records and email the tickets to customers based on the order status (see screenshot).
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Tickets Plus for a test run, feel free to do so! Please let me know if you have any additional questions or if I’ve misunderstood what you’re looking for.
Thanks,
Jennifer
