Hey Ricky,
There is no phone support here, though I can still address your questions! 🙂
The Unlimited Version is just a license type, it does not add features to the individual add-ons. So Events Calendar Pro does not have community submission. Community submission is only available from Community Events. So if you buy an unlimited license for Events Calendar Pro, you still will not have the features of Community Events, and vice versa.
As for whether community-submitted events can be recurring, yes, if you have BOTH Events Calendar Pro (which provides the recurrence features) and Community Events (which provides the submission features) then yes, users can submit recurring events.
I hope this helps!
Cheers,
George
