Even though it is not a direct implementation, I hope this could be helpful:
We just launched integration with Integromat platform, which helps to build automated workflows. We also provide several templates for quick start, and one of them allows to copy google calendar events into WA events. So if you share a google calendar for events submission, then the scenario could copy submitted events into your Wild Apricot account.
You can try this integration by this link https://www.integromat.com/en/integration/2275-copy-google-calendar-into-wild-apricot-events

Bob, for now I created a Jotform (free at jotform.com) and then used Jotform's embed feature to embed the form on a members-only page on our site. I put a link to the form on the page that displays our calendar. The Jotform emails the submission to me and then I create the event. It's not ideal, but it does give the member a standardized information collection format and let's me track and respond to the submissions.
