Hello Mikael and thanks for reaching out!
Great idea! I’m afraid Community Events will not connect with Facebook Events to import events from Facebook but, if you have a moment, it would be awesome if you posted this idea to our feature request forum. This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
Sorry for the bad news but does this help answer your question? Please let me know.
Thanks,
Geoff
