I am considering purchasing Aggregator because I am creating a site that will list all the events from various cabaret clubs in several cities in my Event Calendar Pro. I envision my site to be a central location to view cabaret events in any given city. My question is, does the Aggregator import calendar info from any url (like the website of a club) automatically or does it only work for personal calendars (like google or the like)? For example, I want to include the events from this club on my site: https://donttellmamanyc.com/shows. Is that possible with the Aggregator? Or do I need to obtain special permission from the club to import their calendar? Or is this not actually possible?
