Howdy oakley56fila!
I am glad to see your interest in our plugins. The pro plugin adds recurring events functionality. When combined with the Community Events plugin it will also allow members of the community to submit recurring events. To add this functionality to your current site you will need to get a Pro license in addition to the Community one you already have.
If you are looking to see what features are included in a plugin, our product pages are a great place to go. The Products link dropdown menu in the main navigation bar contains a list of our products, clicking on one will give you a lot of relevant prepurchase information. If you have a specific question that is not answered there, searching through our site or asking the question here will get you an answer.
Does that help clarify our product selection? Do you have any other questions I can help with?
