This was a MobileMe only feature, so no of course it will no longer be there as MobileMe ceased to exist at the end of June last year.
What version of iWeb are you using and where are you trying to publish your site to? If you are using iWeb 09 then you need to either select publish to ftp server or publish to a local folder from the drop down menu or if you are using iWeb 08, you need to select the publish to a local folder option from under File and then use Cyberduck to upload your site to your server.
