Submitted a site but since changed the name - what to do

I recently submitted one of my new sites (MyMazda6.com) and though it has not yet been listed (along with 3 other sites I submitted months ago, but that's besides the point) I have changed MyMazda6.com to MazdaSpeeders.com and changed its purpose. I don't want to submit the site under the new name since I don't want to be accused of spamming site submissions... what should I do?

Just submit the new website to the appropriate category. I've taken care of mymazda6.com .
