putting motion blur on a simple particle effect

Hi all.

So I’m trying to put a motion blur on a particle effect and I’ve come to a point where I don’t know how to proceed. The stage guide says that you can put motion blur on a particle system but I’m not sure where to put it. Does it go within the system somewhere, or just outside the group?
The effect I’m trying to achieve is that each particle leaves a short fading trail.

Also, rendering/exporting has also been an issue. Namely, harmony is freezing and crashing. My computer is more than capable of rendering a complicated scene with particles. Any advice?
Thanks in advance! Cheers!
