New Boards - Can't create new lists & can't delete board

Thank you for your reply, but I think you are mistaken about only being able to create 3 lists (including the Parking Lot).I have a Parking Lot with 3 lists. I just now created a new board. This new board came with 3 default lists (to do, doing, done). I am able to add tasks to all of these new lists. Therefore, I now have SIX lists (including the Parking Lot).I suspect I could create another new board and then have NINE lists, but I won't do that since you say that I can't delete boards yet.The problem is that if I delete any of these new lists, Weekplan will not let me re-create them.Thank you. Again, I'm using Win 7 and Firefox.
