Thread:Project:Support desk/Allowing a user to edit one page, but restrict all others

Is there a way to allow a user to edit one (or multiple) pages of a wiki anonymously, yet restrict everything else to require a login/registration? This is a private wiki inaccessible from outside the company.

Version information follows: MediaWiki	1.21.2 PHP	5.3.3 (apache2handler) MySQL	5.0.95

Thanks,

Wayne
