If you are really that paranoid about cookies just turn them off in your browser but you will find a lot of websites, including this one, one work properly. things like the lights, red folders, your password and username are stored on cookies. If you really want to know what what info there is just look at the cookies.
I have the option set to ask me if I want to accept cookies or not and every time a new one is about to be set I either accept it or decline it. 99.99% of the time they are used purely to enhance functionality of the website you are visiting. A cookie can only be read by the site that set it.
Nothing sinister and a necessary item for many websites that use time sensitive displays such as the indexes on PPRuNe. Now, to prevent a few of you using this thread as an open letter to each other instead of email and to put it in its more suitable forum I am moving it to Computer and Internet issues.
