Barh. I am in a coffeeshop and the wifi has just become very spotty. I have to stop messing for a bit. Joining an event might be a good idea, but there is more complexity there. It would be interesting to see who joined an event, but people might not actually want to join, and yet be notified, or to join anonymously. For that reason, I don't think we'd make a list of people that joined. I think that saving an event might be the way to go. Perhaps with either the option to see only events, or to have a separate list of events that you've saved? It's in YYYY/MM/DD format currently. That's the international standard AFAIK. Is that ok?
YYY/MM/DD is ISO standard. some people prefer DD/MM/YYYY, but i think the ISO makes more sense. It runs like HH:MM:SS on a clock. when an integer "rolls over", the next column is affected.
