you have an interesting thing but I think you should think about finding someone to do the outreach. Im pretty sure brotherhood is harkening back to early union days and that type of thing which falls flat in our modern wierd obsession with language especially around the sexes. Yeah if your older your used to manking meaning humankind and how the old school unions and movements used language but younger folk will be creeped out by the name of the project along with the username. I still think you should always begin making it clear its gpl. One thing to realize is this is most useful for folks the younger they are.
