I wish I knew what this was about?

Hmmmm.....maybe its like making a wish and blowing out all of the candles?

You can move around on the WL due to a number of reasons.

Someone may have had a WL book on hold, then they decided to unhold that book.  They may have had their account on vacation hold & once they are no longer on hold, their WL books are now back in line again.  Or maybe someone before you had a book that they had to mark as RWAP, which automatically puts them back in line to get that book again. 

I know what you mean, Charlotte.  That happened to me last week & I was SO disappointed!  Each time I see that the wishes are being granted & I'm moving up the line, I get excited......so when I seem to be moving up & then go back, it's disheartening!!  

It is disappointing, but I've really appreciated the times when I've received a damaged book, or a book on its way to me has been lost in the mail, and I've been placed back in my original spot in the wish list lines, so there's a definite plus side to it.

From the help center:

Why did I move *backward* on my Wish List?

This happens when another member who was "ahead of you" in line previously  and was taken out of line gets back into line. 

This can happen if a member (or members) ahead of you in the Wish List line:

• Put her account on Vacation Hold (and this book was not set to auto-request).  This will temporarily move you up in line for the book, since Vacation wishes not on auto-request are hidden by the Vacation Hold.  When the Vacation Hold ends, the member goes back in line ahead of you.  This is a very common scenario. 
• Got offered the book but used the Not Now button - this puts the book back on the Wish List in its previous position, on hold.  If (a variable time later) the member removes the Hold from the Wish, that member will be ahead of you in line.
• Put this Wish on individual Hold on the Wish List, and then later unHeld it.
• Got an offer of the book, but the sender canceled it (did not mail it).
• Got an offer of the book, and the sender mailed it, but the book never arrived and it was declared lost in the Mail
• Received a "problem" copy of the book - damaged or wrong, etc.  This will put the member back on the Wish List in his or her previous position.

Please be assured that we would NEVER put another member ahead on the Wish List without good cause--in order to go ahead of others on the Wish List, a member MUST have Wish Listed that item earlier (on an earlier date) than they did.
