any idea how i can add digital post it notes to word documents that can be read on other computers?

I am adding comments to students work in eportfolios and need to write comments for their reference that they can read and consider and then erase.

It’s not quite Post-It® Notes, but Word has a built-in commenting feature under Track Changes. Try this:

In Word versions prior to Word 2007 (Vista):

1.Right-click in the menu area and select the Reviewing toolbar.
2. Click where you want to add a comment.
3. On the Reviewing toolbar click the third button from the right to add the comment.

In Word 2007:

1.Click the Review tab on the Ribbon.
2.Position the cursor where you want the new comment to go.
3. Click the New Comment button

That should do it.
