Personally I don't see a problem with an Australian club but saying that I probably wouldn't join it as I don't see very good discussion coming from it. I may be wrong but thats just my opinion.
Theres already a digimon club so maybe if it dies it could be remade!
Mockingjay I think a nutella club would be to specific to get good discussion going so itd probably die out. Making a Ferrero s.p.a club would probably get better discussion going but im still not sure if itd work. (Ferrero is the company that makes nutella as well as other products such as Ferrero Rocher and Kinder, according to wikipedia at least.)
Alex I agree with your completely! Especially about easier C/P from the username in a sign up form xD
