In SharePoint Server 2010, you can add notes to a
document. These notes are available for other people to read. You can
use this feature, for example, to provide feedback on a document
without actually changing the document and without having to check out
the document or even have editing permissions to the document.
To add notes to a document,
select the document in the web part or list view that displays the
document to switch to the Documents ribbon. In the ribbon, find and
click the Tags & Notes button to open the tagging dialog. In the
dialog, select the Note Board tab. This tab allows you to type notes
about the document or view notes that other users wrote for that
document, as shown in Figure 1.
