Bookmarks, like all information in KeepandShare, can be shared with your friends and colleagues, allowing them to access and use your bookmarks to navigate to great web pages. For instance, if you have created a folder of bookmarks pointing to a dozen of your bookmark music review and music blog sites, why not share these bookmarks with your friends so they can find the same web sites?
Sharing is easy. Click the blue "edit" command next to a bookmark's name, and then use the "Share With" controls:

Either type the name of one or two of your friends into the Username fields, or type in a name of a group (see below) into the Group field. If you want to grant them the ability to edit this bookmark, you can check the edit box. When you're done making your share settings, click on "Save and Exit".
As you've seen, you can control sharing for each individual bookmark. But you can also control sharing at the folder level - all the bookmarks in that folder will be shared identically to the settings you make at the folder level. To set folder level sharing just click on the manila folder icon next to the green folder name, then click on "Edit Folder Sharing" command.
