I'm still using Poser 4 too (with Pro Pack), with the DAZ figures and I'm not even considering getting Poser 5 to be honest. I'm eagerly awaiting the new Daz Studio though as that's sure to compliment the figures nicely :-)

Does anyone have a rough idea what sort of P4/P5 ratio of users there are on here? Just curious as I would like to know how many P5 users I'm neglecting when developing my add-ons!
