No need to yell. Programs such as Raydream, Carrara, 3DS Max, Lightwave, Truespace, and many more can be used to creat the prop. Basically any program that can be used to model something and export it in a format that Poser can use (.obj and .3ds being the two key formats). Poser4 and a text editor are all you need to make a prop poseable. But the different utilities out there like PHI Builder, cr2Editor and Compose can make the process easier. Hope this helps.
