I have a monthly project with the same tasks of list. I would like to set it to repeat after it is completed each month. Is that possible?
unfortunately, that's not possible right now, but thank you for your feedback, we appreciate it and will consider adding such feature in future development.
You're welcome to vote for the request to add the possibility to duplicate projects in our Votebox::
For now, as a workaround, you could use recurring dates http://todoist.com/Help/timeInsert for each task separately.
