Only you can see your old ones. All we see is Sorry but there are no active casting calls for SandyCamel at present
If they were completely deleted we wouldn't be able to revive them if we needed to. On a couple of occasions when I have been unable to match a shortlisted model's availability with my own and the deadline has been fast approaching I have turned Casting Calls back on and sent a link to models advertising availability inside the shoot window. It's a very handy ability to have.
