How would anyone else feel about a pay-to-enter competition? Simple rules:
1) everyone pays a nominal amount (eg US$2) to enter (maybe to a centralised PayPal account or something?)
2) winner takes all - the person deemed the "winner" gets the contents of the PayPal account
3) the person setting the challenge is not allowed to enter (clearly, this person may already have spent years working on their design!)
4) the entries are judged by LMR members and these members must not also be entrants in the competition.
