Javascript and cookies are required for a site I'm currently building.

If they're not enabled, I send the user to a page where it asks them to please enable javascript/cookies in their browser.

I'd also like to provide information to 'normal' users as to exactly what javascript and cookies are - mainly to allay any concerns they may have regarding privacy, security, etc etc.

Without having to re-invent the wheel and write copy on all that, is there some 'javascript/cookie description for dummies' that I can post a link to for concerned users to peruse at their discretion?
