There is bad and good. If they don't like you or you don't fit in, you re just treated like dirt. Some of the organizers are very nice and others are ignorant. I already talked to organizer who had serious trust issues with meeting new people. Well duh! What are you doing on meetup? I guess it's like everything else. You have good and bad but I did meet some really cool people. There are better ways of meeting people. Oh and if you re new to a group and you re not liked, some organizers will delete the event!
