Sivel also known as Matt has announced that he has changed his forum to read only status. Instead, support for all of his released plugins will be handled by the WordPress.org forums. The reason for the move stems from not enough time in the day to handle the support load so by putting it on the WordPress forums, other plugin users can help out. This is a similar move that Viper007bond made earlier this year. Among some of Sivels plugins are: Possibly Related Posts, Better Howdy, and his entry into the plugin competition this year, Ajax Plugin Helper.
