Even faster than google is to look at the right and go to Roy's Poser MAX tutorials, it's in the webring Top 15 and has been so for ages. Phi Builder is available there. Great tool, I could never make the setup room work properly either, EVEN with exact naming I sometimes end up with ungrouped bones :o/ But Phi builder works every time!
