Hi Sean,
That’s an interesting question!
Unfortunately there’s not quite enough information to help me fully understand the scenario. Do you mean that, if a user is logged in, calendar view should only display those events they have RSVP’d to (wouldn’t that stop them from finding events in the first place)?
I’d love to know more so I can guide you if at all possible — though, please be aware that the degree of support we can offer for custom development tasks tends to be limited 🙂
Thanks!
