As a Poser 4 user, I keep a separate pose folder outside of Runtime, but within the Metacreations>Poser folder, for poses currently not in use. This works pretty well for me, although I sometimes forget what's in there as opposed to what's in the actual poses folder. The only reason I'm not buying PBoost is because I want to see what Poser 6 will be like, first. :-) This is an excellent thread. Big thanks to Doug re: the INJ/REM poses idea.
