Thanks! The idea is to use software to promote this reform (as well as Final-Five Voting...which is Open Primaries + RCV)
As for advanced tactics, if you're really into it, Rob Richie, the CEO of FairVote (leading national advocacy org) put this in the New York Times over the weekend. It spells out a bunch of scenarios (e.g. "I want Garcia to win and Stringer to lose.") and how to tactically vote for each.

BUT the point I'd want to drive home is that ranked-choice allows you to be FAR more able to "vote for who you believe is best" than in the more common most votes wins approach (where you have to be strategic the moment a 3rd candidate enters).
