I am a developer who coincidentally has two separate clients that I’m building new WordPress sites for, that need front-end submission for an Events calendar. I have used your free The Events Calendar plugin in the past, and I’m interested in your Community Events plugin. My pre-sales question, does this also require purchase of Events Calendar Pro? In other words, do I need to buy the $149 business license for Community Events AND ALSO the $149 business license for Events Calendar Pro, in order to have front-end submission for an events calendar, on two separate sites? Thank you.
