You need to make it so if someone clicks (Quit Chuunin Exam) then their scroll gets automatically dropped so the other person is'nt walking around aimlessly looking for nothing...
and I dont know if this is in already but make it so if your the only partisipant in the Chuunin exam than you automatically get chuunin. Also if you can lower the time on Chuunin >.> 5 hours is a little harsh especially if you miss it while ur training, half the time I dont even see the chuunin exam announcment. >.>
