I don't contribute as much as I'd like to this mailing list, although I learn lots from reading it, so thought it was time to give a little something back.
As we're in the season of all things sparkly, here are a couple of time-saving particle wipe animation presets I developed for my own use when creating multiple particle wipes in one composition.
The main benefit of using these is that you only have to set two position keyframes for each wipe. Everything else is controlled by expressions, so no need to keyframe particle/second on and off for each wipe.
I've put a download link and full description/instructions in this blog post:
