A few days ago the download counter for the 404page plugin jumped over 10000. According to the wordpress.org stats currently there are 6000+ active installs. Thanks a lot!
Best way to celebrate that is to release a new version! The new version 1.4 of the 404page plugin allows you to edit the custom 404 error page directly from the settings page. A small but effective change. Also the plugin now is available in portuguese language. So currently already five languages are supported.
