I heard of this effort through the Con Anti-Harassment Project, because someone mentioned on an arisian mailing list that Arisia was reported to have a well-articulated, comprehensive anti-harassment police published online and in the program book. Checking out the CAHP page led me to the OSWBEOU [Open Source Women Back Each Other Up] Project (& Gentleman's Auxiliary).
My participation is gender & orientation neutral. While I'd be a fool to not recognize that it is more likely that I might encounter a man harassing a woman. I will not stand idly by and let anyone be abused, no matter the gender of the aggressor or the victim.
