Since the server seems to have ground to a halt;) For those of you that can't access the site, yet, here is the system requirements, as I remember them;) Windows 98, ME, 2000, XP 500mhz Pentium (700mhz recommended) 128MB RAM (More recommended) 500MB Hard disk space As for upgrade prices, in addition to what Legume posted in Post#2: $349-Full version $209-Upgrade from Poser 1,2, or 3 There will also be Academic discounts. Last week when I predicted similar upgrade prices, people thought I was nuts;) Hope this helps those that can't get to the site, yet. hOss69
