We do offer a discount for non-profit organizations that meet basic guidelines. If you’re interested, please send us an email to pro /a/ tri.be and we’ll send you more information.
The recurring events feature is only available in Events Calendar PRO, so you’d need to upgrade if you wanted users to be able to post recurring events via Community Events. Does that clarify things for you?
Let me know if there’s anything else I can help you with.
