Hi Marcia,
Thanks for getting in touch. The answer depends on how you collect info from your promoters and users, and what kind of export capabilities you need, so I’ll outline the various options that we have for you.
We have a plugin called Community Events which allows site visitors to submit their own events to your calendar. This might be a great way to collect information from users and promoters. You have control over the events on the backend of the site. You can learn more on the product page, and of course ask any questions here 🙂
The Events Calendar (our free core plugin) includes a .CSV importer for events, venues, and organizers. This may also help you collect information and add it to your site.
There are a few options for exporting the information as well. You can export individual events to Google Calendar and iCal. You can also export multiple events (for example, one category of events or one month’s events) to iCal as an .ics file. You can also export your WordPress database, which includes your Events Calendar information.
Let me know if I can answer any other questions for you. Thank you for your interest!
Best,
Leah
