Are you referring to the Community Events plugin? If so, please take a look at this section of the new user primer … if it’s something else please let me know 🙂
I purchased the event plugin pro and I thought there was a way for others to add events to the calendar. is that not possible and now I have to purchase the community plugin a well?
No, I’m afraid that’s never been a feature of Events Calendar PRO. It’s not impossible though and if you are a reasonably confident PHP developer (or are working with one) you could put something together. I know that in the past and perhaps even now people have leveraged Gravity Forms to assist with this.
