In a fast-moving Slack team, keeping track of your commitments to others and your personal bandwidth is a constant challenge.  Commit.to is a lightweight yet comprehensive solution to this problem.  Instead of saying, "will do!", use Commit.to:

/committo Send @mbolton the TPS reports by 5pm on Friday. ~minutes

With the due date and a lightweight estimation (which can be 'minutes', 'hours', or 'days'), Commit.to will send you and your colleague well timed and actionable reminders, keeping just the important items in front of you.  Nothing can fall off the radar, and no one else can make a commitment for you.  You have complete control, while giving your team greater visibility.
