welcome :)
start out with what you have within Poser 7. There are a lot of figures in there...clothes, etc etc.
Take your time. Enjoy the program. Don't be afraid to poke around and see what you can come up with...nothing to be afraid of. then after you get the hang of it, maybe go to the free stuff area and dwonload things you;re interested in. No need to buy nore right away. There are sites like crazy all over the web...more free stuff than you could ever use in your lifetime, unless you've found eternal life.

On the right side is the library ... open it up and click the check box..go to figures...click the check to  load a figure ... play with it..mover legs, arms, etc... just go for it :)

Also, there are tons of tutorials, but read the manual...just start at the beginning and go through it. Its all epxlained in there..at least most of it.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
