Hey David,
Thanks for reaching out!
Such an action may indeed be possible. To be clear, though, we have no built-in support for that action or integration with that plugin at this time.
So, to get that plugin to fire its emails and such, your best bet is to reach out to those folks and see if they have any insight on wiring these things together.
I think a big help in that process will be an action that Community Events fires, called tribe_community_event_created. This action fires when a community event is submitted, and can be used to trigger other actions. It will take some custom coding though, unfortunately, so reaching out to those folks for further custom coding support is the best step I can recommend.
Thank you,
George
