We sent this tweet last night:
We would encourage you to check your Facebook privacy settings now that it is easier to undertake. Make sure you have your privacy set to meet your requirements: whether you want to lock it down or open it up.
The default settings before this announcement were skewed to limited (to no) privacy. Those of you that want privacy should definitely take action.
If you go to the link in the tweet above you can get the lowdown on the situation from the BBC. The beeb has also got links in the article to the history of FB privacy and a guide to walk you through the new settings.
