Abstract: A method for communicating in a digital conversation is implemented on a computing device and includes: receiving an interactive contextual emoji from a first digital conversation participant to post in the digital conversation with at least a second digital conversation participant, where the interactive contextual emoji is pre-defined to indicate at least a current availability status associated with the first digital conversation participant, requesting the current availability status from a status application based on at least an indication of the interactive contextual emoji, where the status application maintains the current availability status, receiving the current availability status from the status application, and displaying the interactive contextual emoji in the digital conversation with at least an indication of the current availability status.

Abstract: A supplemental downforce system is shown for a ground working implement having a frame and a plurality of ground engaging row units movably mounted to the frame for up and down movement relative to the frame. The downforce system includes at least one actuator between the frame and each row unit to apply an up or down force to each row unit. The actuators are assigned to one group of at least two groups of actuators. A control system controls the down force applied by each group of actuators separately so that each group of actuators is given the amount of supplemental down force that group of row units needs. In a closed loop feedback system, at least one row unit in each group of row units is equipped with a load sensor so that feed back of the soil reaction force on the row unit is supplied to the control system.
