Did you have a hard time finding a pin because the title wasn't very complete? Did you find the pin but the description isn't very detailed? When you found the pin, was there no description about the back of the pin? There is an easy solution to these problems. Add a comment!
Locate the COMMENT tab that is on each pin listing page and click it. You'll see an area where you can type your comment/information. Type in the changes that you think should be made to the information about the pin and submit. An administrator will review your suggestions and make the necessary changes. The more detail you can share when you comment, the easier it will be for the administrator when they review and update.
Why is it important to comment? If you had a hard time finding the pin, others probably will and your updates could solve that problem for others.
