Before people start submitting their entries, @OP please consider my suggestions:
1. if scoring is only your and your team's prerogative, please set this contest status as the blind contest. For example, send an entry(es) via PM first, then reply to this thread to confirm participation.
2. participants must submit all entries at once, this prevents you from spam submissions.
3. about this point,
we will pay everyone who participates a share from the 3k.
It seems too easy to get a share of this payment for
this typical participant (I doubt he even read the contest rules as he just registered today), it's better to limit it to a few participants, or anyone who sends more than n entries.
