need some tutorials

[musilowski]

Well I've done a tutorial on creating fire with Cascade (the particle system editor), goes through using the most basic modules. Or are you having trouble with some exact module?

I'm also planning to making a tutorial/list on what every module and their options do.

who can give me some tutorials or links about the u3 particle system's every module, u3 particle system help document is ok!
