Hi Fanny,
Thanks for checking out our plugins!
Community Events does not include the recurring events feature, but you can use it in conjunction with Events Calendar Pro to allow your members to create recurring events. If you require users to be logged in to submit an event, they will need to be logged into your site (not Community Events specifically – there would not be separate accounts).
We do offer full refunds within 30 days of purchase, so if you’d like to take Community Events and/or Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
