In a few days, there will be a second app option named "mini_collatz" which uses the same apps but checks a much smaller range of numbers per workunit. Those with fast GPUs should unselect mini_collatz in their project preferences as they will likely run out of work each day if running the shorter WUs. Those choosing to disable the longer Collatz WUs should make sure to check the "If no work for selected applications is available, accept work from other applications?" option so they will continue to get until prior to the new app being enabled.
