-EDIT-
To show off the power of the editor...heres two more effects i made with it..they took about 1 min of playing each to get right.

Yeah I will do...i'll give a rundown now though...it is a little hard at first but once youve got it youll be amazed at how easy it is to get different effects.

Fequency: How many particles are made per second

Lock to Object: This is if you want to set the particles to always start at the position of a certain object

Emmiter Width/Height/Depth: this sets the area in which the paritcles appear if i set them all to 0..the particles always appear from one spot, for fire this was unrealistic to i set the width and depth to 7 (in the pic above) so the particles will appear anywhere withing this area..this is why the base of the fire is wide.

StartSize: The size of the particle when it first is made
EndSize: The size of the particle when it first it dissapears

Life: How many seconds the particle exists for before dissapearing

StartFaded: how much the particle is faded when it starts...at 100% it looks normal at 50% it looks half as bright...if the object is ghosted (transparent) then this makes the object seem to fade away
End Faded: Sets how faded the particle is when it dissapears

Starting Speed x/y/z: sets the speed that the particles are moving at when they are created

Acceleration x/y/z: Sets how fast the particles accelerate as time goes by

Bounce: A complex feature...if a particle hits an object when this has been set the particle will bounce off..this can be used to make very realistic smoke effects as the smoke will curl round objects as it rises. setiing it to 1 means it bounces of with all the speed it hit the object with... 0.5 means half the speed and so on.

Ghost: Ticking this makes the particles transparent.

Rotataed ?: ticking this means the image used for the particle will be rotated so giving the impression each particle is slightly different

Zwrite?: as a rule you always have this ticked....its very complex to explain, it basically makes sure that the particles wont look strange as they touch each other....but to fully understand needs programming knowledge.

Set texture: This lets you pick the image to use for the particles...this is how you make it look like fire or smoke or anything you wish !
