Event Registration

We are using EventBrite for event registration. So far all of our events (Online (controlling distribution of Zoom link - through registration) or Onsite (controlling in building RSVP limits for COVID safety)) are free - with a "suggested donation" and a link to our website donate page. It has been somewhat cumbersome/clumsy for us and confusing to our members and prospective members so we are looking for an alternative. What are you all using?
