Hi Julie,
Thanks for writing in!
That is correct: Community Events and Events Calendar PRO are two separate plugins, each with different features and non-overlapping features.
Community Events adds a submission form to your site that others can use to submit events to The Events Calendar.
Events Calendar PRO adds several features to The Events Calendar, including recurring events, custom event fields, additional calendar views, venue and organizer pages, shortcodes and more.
We’d be happy to exchange your license for Community Events instead of Events Calendar PRO, if you would like. Please let us know by filling out the form on this page and referencing this thread in the comment field.
Cheers!
Geoff
