You can find boards by searching CoughDrop, browsing popular boards, or by following links others have shared through external web sites. Favoriting a board helps the author know how many people like and appreciate their board, and also makes it easier for you to find and access in the future.
Star that board
When you find a board you like hit the "Star" button to favorite it.
Boards you have starred will show a filled instead of an empty star icon. You can see the total number of people who have starred the board as well. If you ever want to un-favorite a board just hit the "Star" button again and your star will be removed from the count.
Starred boards on your profile
At any time you can see the boards you have starred on your account summary page.
