Hi there Derek,
Thanks for getting in touch with us! Interesting idea š with some more information we can turn this into a feature request.
Just to confirm, you are referring to the ability of importing tickets create for events in MeetUp.com and linking them from the calendar website? If this is the case can you describe a bit more what you would expect of this functionality? Just a button indicating there are tickets available for purchase in MeetUp.com or would you like to see a deeper integration?
Please let me know about it,
Best,
Nico
