Extension:UserPageEditProtection

The UserPageEditProtection extension restricts user page edit to the owner of the page (the user) and users assigned to groups that have user page edit access through $wgGroupPermissions. This effectively provides users with a group of protected pages, since this protection extends to any subpages of the user page (i.e., User:Hoggwild/sandbox1). Any user assigned to a group with view rights to user pages can read a user page, but only an authorized user may edit it. This extension has no effect on user talk pages.
