I'd like to know if it's possible under the current system to require contributors to register a user account before they may make edits to any pages. I realize that this isn't exactly in the spirit of the wiki system, but we've had a problem with a user lately who hasn't been paying attention to our repeated requests to follow the rules. One of the options we'd like to consider is requiring contributors to register first.
But, is that possible using the current software? How could I set that up? I've taken a look at DefaultSettings.php, and I see the variable $wgWhitelistEdit and the array $wgWhitelistAccount, and I was wondering if those have anything to do with what I'm looking for.
Thanks, Dan
