Abstract: In one embodiment, a method includes determining that a first user registered for an event. A first user identifier for the event is determined upon the first user registering for the event. The first user identifier is associated with the first user. A message is received from the first user. The message includes a second user identifier associated with a second user. The second user identifier is determined for the second user upon the second user registering for the event. A computing device automatically connects the second user and the first user using the first user identifier and the second user identifier.
