A system includes a processor and an interface. The processor determines that a first user takes a first action and a second user takes a second action, where the time period between the first action and the second action is less than a threshold. In response, the processor causes the system to transmit at least one of a suggestion associated with the first user for display to the second user or a suggestion associated with the second user for display to the first user. In response to the processor causing to transmit the suggestion associated with the second user, the interface receives an indication that the first user approves of the suggestion associated with the second user. In response to the processor causing to transmit the suggestion associated with the first user, the interface receives an indication that the second user approves of the suggestion associated with the first user.
