A system, computer program, and method for location-based social media interaction between a plurality of participants. If a folding priority mode is not set on a selection screen displayed on a display unit of the sheet processing apparatus, a controller of the sheet processing apparatus determines whether or not the number of sheets of the sheet bundle indicated in sheet bundle information is equal to or larger than a threshold value. The microfluidic nozzle array devices are fabricated using an injection molding process and find particular utility in a wide range of applications, including but not limited to nanosprayelectrospray applications, mass spectrometer applications, optical spectrometry applications, spotting applications, etc. In one embodiment, the DGRC provides a transmitter, an integrated display screen, game-related selection buttons, navigation buttons, a roll button, a timer button, a score button, and a media slot.
