Submitted 6 months ago, should I resubmit, has it been rejected?

I submitted my site 6 months ago to the same category as which my previous site was resident. The new site is a duplicate (in concept, but not in name) to the previous site, thus I felt this was the appropriate category. My new site has not been accepted, or it has not come up for review, I am not sure. Should I resubmit the site? If it is rejected do you notify the submitter? I have heard that resubmitting is not a good thing?

Thank you,
