We try to keep the tutorials on each task updated, but sometimes it's useful to have space to explain things in more detail.
I've noticed a few people mentioning sheets with multiple dates listed per performance. In these cases, just type in the date for the first performance. For now, _____WB$wombat$check$this$function_____(this) should be enough for people to find the performances. If there was demand for it in future, we could make a separate task for noting and transcribing repeat performances.
