Thanks for the privacy doc. You're not bad at all with a Wiki ;)
I'm gonna move it to the right URL, as 'Category:' pages are automatically created when you add [[Category:XXX]] something at the end of a page (and to add a page to a specific category, you just have to add the Category at the bottom of the page so that then it's automatically added to this category) and I will do some tweaks.
