I've used this feature previously and when I went to use it tonight it is no longer there.  Did PBS get rid of that feature or could it be a temporary glitch?

If you go to your bookshelf and click on a book, you will see the Mail To a Friend feature there.  But you can also use custom DC to create a label.

When I click on any book on my bookshelf none of the books coming up show the Mail to A Friend Feature.  Its been in the upper right hand corner but there is no link.  I was trying to use this feature since I can include postage on it and I wanted to blue box it tomorrow.  With Custom DC I can only do the DC and would have to go to the PO and they won't be open until Tuesday - Monday's a holiday.

ETA:  Problem has been solved.  I had put my account on Vacation Hold and when you do, this feature is not available. 

I just checked and my posted books do have the Mail To a Friend link - not sure why you don't see it on your posted books... It's a text link, not a button, so it doesn't seem like it would be a browser-related issue.

Thanks Melinda for checking on your end.  I figured it out. I had placed my account on vacation hold, getting ready to head out for a couple of days, while trying to still mail books out.  It appears if your account is on hold the text link is not available.  As soon as I took it off vacation hold I could see the link!!
