A group, including Aman Gupta and others known by their usernames @tmm1, @atmos, @sr, and @defunkt, is visiting Amsterdam and plans to attend the amsterdam.rb meetup at 17:00, followed by a social gathering at De Bekeerde Suster at around 21:00, where they can be identified by Octocat stickers. They will be hosting the event and covering the cost of the drinks.
