by midnight on the 13th do you mean the end of 06/13? Cause technically it's the end of 06/12.

Good question. How about by 11:59pm est June 13th.

"The 11th hour on Friday the 13th" sounds good

if I wouldn't be so busy, I'd offer to make you a theme myself. (I've always had a problem looking for a suitable theme, made them myself)

this is a cool way of crowdsourcing.
