Well?
Either get an account at an upload site or make it a torrent.
Dunno...Rapidshare or 4 Shared, something like that, I would guess. You'd need WinRar, too, probably, and you might have to split it up. I don't know how big a file you can share like that. Maybe do some research on those two choices...sorry, I don't have any more info for ya. I just know this little bit b/c I'm in a group that sends 'shares' and that's how we get them. Oh, there's another one MegaUpload - I think it and 4 Shared are free ;)
I telled you already.
