It
is a web site. I'm sure they have limited time and limited budget. I doubt anyone involved has the time (or patience) to not just sort through what could be thousands of digital images, but then sort through, and scan physical prints as well. What do you think Sean would say if we were to send him our prints to be posted rather than scanning and submitting electronically?
(Umm... Sean, why are you looking at me like that?)
All the power to them and I hope they get (and show) some truely great material.
Just to play devil's advocate
and open a whole can of worms; what do you think would happen if "Men in Photography" was to hold a contest open only to <gasp!> "Men"?
