You can also pin one Note on your playground.  A pinned note is the note you want everyone to see first when they visit your Playground. This is often used to pin your personal information or best tutorial to the top of your list of notes found at "u/[username]" and "u/[username]/pages".

Below is how a pinned note appears to everyone who views your page.

To pin a note, navigate to the note edit page and click the 'Pin Note' button on the right-hand side of the page.
