According to a Mashable report, users can pay the social networking company to send a message to Zuckerberg that would appear in his Inbox - it would otherwise normally appear in the 'Other' folder.

“In our tests from multiple accounts, it appeared to be the case that users only get this message if they're not one of Zuck's 16 million followers. That, however, could still be coincidental,” noted the report.

The report further points out that the new feature could be an upgraded form of the $1 pay-to-message plan that the social networking company has been testing for quite some time. The company had previously hinted it would be experimenting with other 'paid' features.

The reports of Facebook's new service comes days after the social networking site rolled out new and improved controls for content management on the social networking website. The update includes a new icon on the toolbar, which gives users access privacy settings from whatever page they are on.
