i agree with most of the points already stated, as cash prizes instead of hardware, possible 1st 2nd 3rd prizes.

I entered a few of the challenges. Some i found quite entertaining. Others i felt they didnt offer anything useful to me. Which was disapointing.

Maybe as a possibilty for future challenges we could have a list of 4 or 5 options that could be voted on during one challeneg as to what the next challenge should be.

So during this challenge make a poll as to what the next challenge should be... then you would know at least a majority would like it.
