This went live to the general public yesterday:

http://archivist.incutio.com/css-discuss/

It's an archive of everything sent to the excellent css-discuss mailing list since the list started in January, complete with a search engine. If you have a CSS problem the chances are it's been discussed at length on the list so the archive is an invaluable resource.

If you spot any bugs or have any feature requests for the archive drop me a private message

Cheers,

Simon
