How to convince your parents for a Facebook?

[Ashes]

How old are you? A nice compromise for preteens whose parents are unsure about facebook is to allow them to have your password for a few years, that way they can check in to see what you're up to. Regardless they should at least be your facebook friend so they can see all of your public activity.

If there are things your sister posts that they do not wish you to see, you might want them to talk to your sister about adding you as a limited friend, that way she can control the content you can and can not see. Or if necessary you could just not add your sister at all for a few years, until they feel you're old enough to view the content she's posting.

Talk to them about privacy and limited availability.
