Really changing the skin of Facebook and Tumblr

There's a lot of fake groups telling they will say to you how to change the skin of facebook if you accept to join a group where they'll ask you to share a lot of your info and invite all your friends before they reveal you the secret.

There's no secret, just go to UserStyles.org for Facebook and select + install the style you want.

You can use it with Tumblr too, just go to UserStyles.org Tumblr section.

And stop sharing your info freely on the net!
