I asked for an extension because I am moving this month and have to move furniture from one house to another. It is stated on the battle page that I asked for an extension & that it was granted. I feel your pain though, as I often have to write during my works hours or cancel plans just to get something in by a deadline. Hell, my GC Final, I had to fly out to UK the very next day. I was juggling between work, regular errands, packing, making sure I got my flight information down & writing bars for the most revered battler on the site.
If you need more time, ask for it, I am sure @
Student would happily grant you an extension if you tell him a reasonable time before the deadline.
