That's true and there are some secret swaps on here so they hide their names so others cannot figure it out and later forget to add them back. And then I suppose theere are those who do not want us to know. If they do , like you said, it is in a post or perhaps when they join a swap.
And there are those who, and I agree, would worry about someone looking up their name and addres and coming to their homes to steal their stash.ROFL......
