Blind Playtesting

I'm working on getting some playtesters who'll try playing my game with no contact or help other than my written rules.  I have a couple folks in the pipeline now, but I'm looking for others.

Some of my early playtests were essentially blind trials - friends and family to whom I sent copies around Christmas of last year.  They all misunderstood the rules in different ways and to varying degrees, which is no good.  I've rewritten the rules now, adding a number of pictures and examples, so I want to see how it goes with a new group of fresh eyes.

I've got two new folks whom I've never met, one an acquaintance of my father-in-law, one a guy from Boardgame Geek, so hopefully I can get some advice and input from people who don't mind giving me the cold, hard truth.  Assuming they write back, and give me some feedback, this will be well worth the investment of sending them a free copy of the game.
