Why is there no group listed for Leytonstone? Do the Restart Parties there belong to another group? If so there’s a discovery issue for such instances.
As there isn’t I’m posting here (@ugo you’re listed as the host on meetup). Is it correct that the Restart Party starting there on Saturday, September 15, 2018, 11:00 AM is a marathon one running for 27 hours non stop? If not, you may want to edit the Meetup details.
Update: I’ve now found the Leytonstone Restart Party through Events and that way found it belongs to the Restart HQ group. However I also realised that ‘group’ discussions do not match the groups used for events so the London group is probably the best place to post this.
You may want to consider using two different terms than overloading groups for both container of events, and local discussions as they’re not the same.
