What does it mean when a book on your wishlist is pink and says, "on hold"? How and when does it come off of hold.

Thanks!

It means your wish is on Hold and you will not receive offers on the book. The Hold needs to be manually taken off of Hold by you. To do that check the box next to the book the go up to the right where all the buttons are and find the UnHold button and click that.

Thank you! I can't believe I missed that.

The system will sometimes automatically put books on hold.  Such as when one linked version of a book is sent to you.  Or if a book went lost, it will be added back to the WL in the same place, but on hold to give extra time for the book to arrive.
