Just a word of warning guys - there's a scam doing the rounds where you will receive a message from one of your Facebook friends inviting you to install a Dislike button to your Facebook account. DO NOT DO THIS - this link will install a rogue app which will take control of your account posting messages to your wall and sending invites to your friends.
I have had two messages from people in our facebook group today so it's possible their accounts have been compromised and I'll contact them separately to check
