Using a plugin

[Emmett Gray]

I've R'dTFM but I still don't know how to do this. I'm using 
RevMedia, if that matters. I've downloaded Rinaldi's auto-save plugin 
and want to use it in a particular stack. Where should I put it/load 
it (so that it will be always available with that stack if it moves 
to another machine)? How do I invoke it so that it's invisible? If 
it's invisible, how do I set the interval?
