With the release of WordPress 3.0, the MU functionality has been integrated, marking the end of the WordPress MU project.
This forum, where we've lived for many a year will shortly become frozen in time. It won't be possible to post new entries here, but it will be searchable and you'll still be able to browse it.
Further queries about WordPress MU and the new MultiSite capabilities of WordPress should be made on the MultiSite forum on WordPress.org.
Thanks for all your help over the years, please mind the step on the way out and don't forget to switch off the lights.
Donncha
