Thanks, everyone.  This is helpful.

What kinds of issues is Poser 7 still encountering at this time?  I recall reading that some people were having trouble with crash errors not too long ago.  If there are still serious issues, I'd prefer to wait until a decent patch has been released.  Bitterly I recall lost work in P5 before it was patched up nicely....

I have the free V3, but haven't used her for anything beyond testing development for TDMT.  I'll look into V3 add-ons, then, as well as V4, Miki, and Aiko.  (Wait, I also have the free M3, Aiko and Hiro....)  I'd had the impression that Miki's mesh has asiatic features - which isn't bad, but it means I'd have to alter that for my primary use characters (assuming I can effect a conversion).  Does Miki have much by way of character shaping morphs?  (Or, for that matter, does she have a catsuit?)

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
