Sometimes you are interested in something that is happening on the site, a News story, or a post, or even a song you posted in the Music Library. If you want to bookmark a page or be notified if anyone comments on your post (or any post for that matter) just use the Notifications selection at the bottom of all the pages.

I use this feature often if there is something that I found interesting that I want to refer back to. It is faster that using the sites search feature, sometimes.

Once you have selected to be notified of something you can retrieve those notifications and bookmarks in your User Menu under, you guessed it, Notifications.
