Thanks for the great responses everyone.
I have e-mailed a pair of links to everyone who has responded with interest in reading over the document (whether or not you can playtest it, feedback is still helpful). I used the e-mail form via Yahoo Groups, so it should have gone to whichever email address you use for the group.
I have created a separate Google Docs document (linked in the email) with some general information bout what I'm hoping to gather from showing fof the document. Please feel free to either email me your responses directly or append them to the Google Doc for all of the other contributors to see. Also, let me know if you'd like a name or pseudonym listed in the credits of the final publication.
If you have any questions or comments let me know!
