Please don't resubmit any more. The one that the previous editor found will be reviewed. All other submissions will be deleted. Usually a resubmission actually delays your listing, as an editor with only a few minutes to spare on a category may just go through and delete obvious spam, and the _oldest_ submissions of a site that has been multiple submitted. Editors reviewing sites and adding descriptions will usually start on the oldest, so by resubmitting you effectively put yourself at the back of the queue each time. Submissions across multiple categories, and of deeplinks in a site will also lead to all the other submissions being deleted.

>> I have not been notified of any rejection..
Editors have NO obligation to communicate with submitters; sometimes there isn't time to edit all of the submissions let alone write to someone about their site. If a site fails to be listed, it is usually either because no-one has reviewed it, or because it has been reviewed and rejected.
