Thursday midnight is not much of a deadline if people know they can easily get 12 more hours (they might not have any problems posting in the first place either!)

The point is, it is unfair to the guy who posts first and on time in more than one way - I mean, they should have the benefit if anyone for at least posting on time....

Again, I will say that if you want the extension to be given it should be requested before anyone has posted...not whenever someone wants it, because rules are there for a reason - this additional one will be abused, you might as well say verses are due Friday 12.00am for everyone instead of this - but rest assured people will still want extensions because its not about 4 days not being enough, but people wanting to play around with the rules - and the only way to deal with it is to have a strict deadline
