Is this new or have I just not noticed it since they added new features in AUG?   On my bookshelf I now have a new button that says "send to a friend".  Really neat cause it will let you print a mailing label for the friend (whether they are a PBS member or not) and remind you to mail it!

They do like to move that button around! It was on the Bookshelf when I joined. Then they moved it to the Book Details page. Now they've apparently moved it back to the Bookshelf again.

They did do some tweeking to the Mail to a Friend option recently. You can now use it to mail any book, not just one on your Bookshelf so members can now use PBS postage to mail books that they are not posting into the system :)
