All the RTFM sentiment around here would makes sense were the Poser manual not the most useless and sensless piece of tehnical writing that I have ever in my life encountered... the Chinglish manual for my Megnovox TV/DVD is more enlightening. I found that the Poser Revealed book promoted by EF was simply an attempt to translate the manual into a natural language form but was equally useless.
