And then there's the other definition of "free" which is when something is unattached/not associated. If you can be "free of disease" (at least I think you can
) then something can be "free of charge."
My dictionary has a chunk of meanings for "free" but I guess my main point is, it doesn't have to have connotations of money. It can, in fact, be money-free!
I agree about the importance of proper grammar, or at least proper spelling, though... how does anyone expect to be taken seriously? That's one of the things I adore about this fandom, actually -- the GE's at the archive keep all our fanfic very clean, grammar-wise. As opposed to some of the horrors I've read over at fanfiction.net. <shudder> But even there, you have to have the story in halfway decent shape before you send it in.
