Shindig requires ???? What does that mean ??

Hi everyone.

On a working profile, I noticed that right above the - POST TO WALL - Box there's a line which reads:

Shindig requires the curl extention, see http://www.php.net/curl for more info

What's up with that message? Does it have something to do with the Post to Wall feature? Does something else need to be installed for D7?

Thank you.

It would appear that you must have cURL installed and enabled on your server. Contact your web hosting provider for more information.
