I'm a girl (and an engineer), and I applied for the summer round this year with http://wordchuck.com . I never got a response from YC after submitting my application, which was a bit disappointing. I haven't had any trouble launching and getting traction on my own, so don't get discouraged, no matter what happens with YC :) That said, WeddingType looks like a terrific idea, and I hope you do get accepted!
Summer 2010 was the first time we accepted late applications, so we were still figuring out the procedure. We'll probably email all the late applicants from now on, in case they miss an announcement. Sorry if we kept you hanging.
