True! It's the prompt to enter data when you're getting close to the edge. But there's more…
Once upon a time, the only way to update your goal was by email. So if you reply to that email with a message that looks like:
^ 1 "I did the thing. Yay me!"
then it'll add a 1 to your goal for today, with that comment.
^ for us is a special 'day of month' that always means 'today', and in this case the
1 is 'today's number', i.e. the value of the datapoint.)
PS: if things ever go horribly wrong because of confusion rather than through genuine not-doing, then even if you've entered a cc we'll put things right. Our ideal is for the motivation that Beeminder provided up until the derailment was worth more than the amount paid.
PPS: any time that you derail, we'll send another email to check whether it's really true. That's the one for excuses and genuinely unavoidable reasons.
It's super valuable to have you here asking questions with your newbee hat on. Thanks!
