I just saw that there are two contests planned on Sunday: one only div2 and the later one div1+div2. Don't you think it may be too much? Maybe it would be better to move second contest (div1+div2) to another day, where there isn't any contest planned?
Both of them are online editions of other offline contests. Take them as gifts to the community. And if you are not comfortable with the time, then just skip them.
