@Mohit Once 75 entries were reached, the 'Submit' button changed to 'SUbmit (Queued)' button to indicate that 75 entries were already reached. It is upto a blogger to submit or not when submissions are queued.
It is not advisable that the submit link be closed immediately after reaching 75 or (80-90) entries because if they there is always a probability that vouchers may be increased. Someone (A) who comes at 12:30 may be a submissions closed message. And if IndiTeam contacts parachute at 2:00 and they receive a positivereply at 3:00 , they will reopen the submissions. Then a person (B) who comes to submit at 3:00 will be able to submit gets the voucher. But as per FCFS, A should have got the voucher and not B.
