Urgent Security Problem - how do I disable the link that allows sharing on social networks?

Hi
Please can someone help? If someone presses the Share link (beside the Actions!) link then people who are not members can see what is only for the members, not the public. How do I secure my pages so they can't be shared on Facebook, Twitter etc? Please please help. I have already asked but got no replies.

Where? through posts or advertisements?

Hello,

Zoids, it's the "share" button near the "actions" button just above the users' avatar

If the thread/forum is in a section where guests cannot see, anyone who is not logged in cannot see it, even if they are given a share link.

For example, if I were to give u a link from my "admin only" room on my test forum, by the "share" button, you won't be able to see it as ur logged out, even if u were logged in u wouldn't be able to see it, because you don't have the permissions to see it; your not an admin.

If I remember correctly, I don't think you can edit the share links with template editing either.

Thanks Darren & Zoids. Yes Darren you are talking about the right link'/button. Even in a memebers only area if they click on that link they can send the whole page to Facebook, etc.

What is the point of having a members only forum if it has this HUGE SECURITY risk? What can be done?
