I wonder which information is stored in the cookie als some users are complaining about losing the configuration after they deleted all cookies

For guests, most things are stored in cookies, but for registered members, most things aren't. The only things I can think of that are stored in cookies are: forum specific passwords, whether streams are set to expanded or collapsed, which categories are collapsed on the forum index, sorting options and editor backups (actually they're local storage, but it is often cleared at the same time). There will be other things that I haven't thought of.
