When a WL book is posted, requested and accepted - then the sender clicks the "cannot send" button - I thought they had to give a reason?  When that happened to me it wouldn't let me click out of the window until I typed something in the box.

I just rec'd a "sender cannot mail" message from PBS, but there was no explanation or comment.

I'm not positive, but I think they only have to give a reason when they decline to mail a book as it is requested from them.  If they accept it, and then click on cannot mail, I don't think they have to give a reason.

I think if they do that (what Julie said) then the email will have a line that says, "The sender had this to say .... " and the comment they write (even if just a period) comes after that.

Well, either way, I guess it doesn't matter much. I just wondered if something had changed. It's been a long time since I  had to use that feature.

If you click "I Cannot Mail" before you accept the request, then you must provide a reason. It doesn't have to really say anything though.

If you accept the request and then click Cancel Order, there is no place for you to enter the reason.
