A bit of ambiguity in the rules, the bit highlighted in blue.

I assume that means a maximum of five entries across all 5 categories. So two 3D entries, plus 2 Photography entries, plus 1 Writers entry would be okay ?

Or does it mean that if you want to enter more than one category you're only allowed a maximum of one entry per category, but if you limit your entries to a single category you're allowed a maximum of 5 ?

And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
