I just installed poser 5 again, and i realized i forgot it all, how do i make hair, and how do i get it to come and sit on top of the head? and how do i get the clothes on?

Load a figure from the Library. Hair can be a figure, prop, or dynamic. For figure hair, you add it to the scene (double checkmark at the bottom of the library - doubleclicking will try to replace the current figure). Then you conform it to the destination figure. For prop hair, you double-click it with the destination figure selected. If should be automatically parented to the figure's head. If the hair not designed for the figure, you may need to adjust Scale/Trans/Rotation. For dynamic hair, refer to the manual please. :) Most clothing items are figures, conforming figures (having the same body parts and joint parameters as the destination figure). You add them to the scene the same as above and selected "Figure->Conform To..." to select the destination figure. The clothing item should be designed for the figure to which it is to be conformed otherwise things may get messy.
