Get a club hedquarters, find a few Juve fans to join the club. Equip the quarters with Juve shirts, flags, scarves, get a TV and a channel that shows Juve games, organise watching the game together at the headquarters, and voila. There you have it. If you have enough members after a while you can organise bigger things, maybe going to a really important match (the CL Final for example).
Zlatan pretty much got it right. Hey, that gives me an idea. Since Juventuz is sort of our own fan club, why doesn't anyone who goes to a juve match make a big "Juventuz" banner like those huge fan clubs do
No, no, of course not. UNLESS you're charging for admission and using copyrighted materials such as videos or whatnot, though these copyrights will usually belong to independant parties, rather than the club itself. UNLESS (again) you're e.g. selling large laminated prints of players that you've taken from the juvenus webiste, or something like that.
