Hi Larry,
Thanks for your interest in our plugins. At this time there is no built in way to charge for premium listings, or to make some events stand out as you describe. Our Community Events plugin allows site visitors to add an event, but the events will appear the same on the calendar and there isn’t a built in charge for adding events.
That being said, it may be possible to do what you’re looking for with some complex customizations of our plugin(s). We wouldn’t be able to assist you with that, but we’d be happy to recommend some developers.
Best,
Leah
