errr...excuse me...

I wanted to know what is the exact last submission date. I have already submitted my posters assuming that 3rd was the last date (as that is what the MEIFF website says)! I wish if I could re-work on one of my posters I believe I could make it much better. Due to lack of time I had to submit my poster without any self-stisfaction! Is there something that possibly could be done here?!!!
