What are cookies

Thanks Mark, I think I will continue avoiding them as much as possible, I am not comfortable with people or sites I don't know keeping information about me

You re well advised to avoid sites you are not comfortable with. I often leave sites that don't let you see what sort of cookies they are storing but I think most sites use cookies to some extent.
I've just looked at my PC an it shows that garden and gossip has 6 cookies there and growfruitandveg has 12, so likely you have some.
