I did not realize there was a separate place for them. How come some of the swaps disappear and some don't from the see all swaps list? I thought it was people who were deleting them

Yes, in the past they had released almost immediately, but these have been there for weeks.

my user name is karenmsmith77 . I do check back regularly, and I have lots of items listed, but I have only found a handful of things I want.

I agree with Terri. The problem is people don't seem to be including much details in the open fields. And it took me a while to figure out that there was a separate tab you had to click to see the size. It would be better if it were all on one page.
