Brion: Some of my friends in the open-source CMS community have created a movement called "GoPHP5" which will eventually reside at GoPHP5.org. We're trying to encourage projects to -- as of February 2008 -- drop support for versions of PHP prior to 5.2. This would not mean older versions that support PHP 4 would be abandoned, just that new releases would only officially support PHP >= 5.2. This is an effort to have web hosts support modern PHP versions. Right now, there is little incentive for web hosts to upgrade because so many web applications support PHP 4 and old versions of PHP 5. We'd like to get MediaWiki on-board. Because the current version of MediaWiki already requires PHP 5 and runs on PHP 5.2 without problems, this would not be as jarring to MediaWiki as it would be to projects that still release new PHP 4-compatible versions. Currently, we're in talks with Drupal, Joomla, CakePHP, Symfony (already in), Symfony's partner projects, Gallery, and WordPress. Thanks, David
