I didn't realise that Meetup charges for use. However, this explains something I have seen that maybe BrumTech/BirminghamIO can do - make a single meetup group, and have all sub-meetups under the umbrella. Then there's only one account to pay the subscription and, as an added bonus, only one meetup to actually subscribe to. Yes there may be a fair amount of 'spam' for people just interested in Docker or JS but usually people want to find at least three or four different meetups.
Where I have seen it before, for reference, is the Birmingham Board (and Card) Game Enthusiasts meetup group. I joined the group and fair enough there's plenty of events I don't care about (Solihull, Kinver, etc.) but it's really good to have the vast majority of all Brum-based board game meetups pushed to me.
Does this sound like something sensible, or have I missed the point?
