Edit: Thanks for help! Admin welcome to delete thread to avoid clutter if they want, not that we have much these days

The site being what it is, there's generally an expert on every damn thing here. Here's the problem. There is a newspaper, this one and they've recently reconfigured it so comments can only be made via facebook. I virtually never use facebook but I have an account, and I'm getting emails asking me to reply to some remarks and I have and I can see them, but no one else can and their invisible even on my other computer. There's nothing in the FB FAQ etc, does anyone have any idea what could cause such a thing presumably on my end? Some setting or change?

Anything, everything, say it if you got it. Thanks
