Yikes, I didn't realize that either and am using P5.  Now, I'll have to find MorphExchange.

That's not a good move on EF's front to ignore all their P4 & P5 customers. I haven't heard any great things about pmd files, so I don't know why they'd stiff customers who haven't upgraded. It's one less reason to want to pay for their figures and I haven't been incentivized enough to buy from them as it is.
