I remember someone asking about this in IRC a while back and I forgot to bring it up until now.
If you go to the wiki and click "Mailinglist" you get here: http://m22.egenius.com/cgi-bin/mailman/listinfo/silverstripe
Clicking the "SilverStripe Archives" link results in this 404 error:

Just wanted to let you know so that you can fix it,
