If you have a task that you do over and over again - for example every Monday I do voting on Pioneer - then use the recurring actions feature to capture that. You can set a task to reoccur daily, weekly, monthly or yearly. That means when you check something off, we'll clone the task and set the due date one day/week/month/year in the future.
If you no longer want the item to reoccur, select 'Once' and next time you check it off we won't clone it for you.
