Thank you for pointing this out to me, and sorry, that I was not around here for some days to comment.
That really sounds promising. 
But at the moment, we do not have the AI Chatbot active in our forum. I am still struggling with guessing how much this would cost us to get an API key from OpenAI. As we run our community in a non-profit way and do not charge, we hardly get the server and domain costs out of the few donations and other stuff like this. So that is an important topic for us. 
The link to the answer in the post with the example calculations does not work anymore. Can you tell me where to find it?
And besides the AI Chatbot integration: Are you thinking about putting a distance information into the plugin as well? So simply showing the distance from the current logged in user to an event or to another user - if both sides have set an location? That was the simple way it was handled in the location plugin for phpBB we used before.
