Hey tony, thanks for the note and for checking out our plugin. Happy to answer these questions for you:
On the issue of reminders, assuming you’re speaking about The Events Calendar PRO: the plugin doesn’t actually have a built-in reminder functionality at the moment. That’s a neat idea and something we may implement down the road but we have no plans for it on the immediate roadmap.
When it comes to setting up recurrence patterns: “First Monday of every month” and similar patterns are definitely possible. “Every other Sunday” isn’t, in that wording, but you could probably accomplish the same end goal using our custom recurrence patterns. Have you checked out this post providing a detailed look at recurring events (https://theeventscalendar.com/pro-2-0-a-detailed-look-at-custom-recurrence/)? It may also add some value.
Hope that helps. Let me know if it doesn’t, or if you have other questions,
