There are some good basic tutorials at Fallen City, and you can search the forums here for the work of geep, who gives great tutorials. If you're lucky, the doctor himself will pop up with some links - I can never remember them. Since you're using Poser 3 in a world dominated by Poser 4 and Poser 5, you might try my tutorial on the subject. Your poses are probably being affected by IK (Inverse Kinematics) which Poser applies by default to new figures; this tends to stick their feet to the floor. Go to the figure menu, and uncheck all instances of inverse kinematics that apply to your figure. Welcome to the mad house. It still isn't too late to take up stamp collecting. ;)
