A board is a place where you can store your tasks and lists in Rindle. In "My Boards" you will get a high level overview of the boards in which you are participating.
To find "My Boards," click on the Boards icon on the left hand column.
From the My Boards menu, you will see that the default selection is Boards, which shows you the list of boards you have created or you are a member of.
You will also be able to navigate to Templates or Archives.
The Archive will direct you to a list of archived boards that you originally created or are a member of. Archiving a Board keeps your digital workspace clean and uncluttered.
