Dont have a wii, no desire to even try Brawl. However I just have a question for the OP, why hawk refs for usenet-news on GBAtemp, I am not sure its such a good idea, i mean usenet has a greasy underside that really i dont think people with little to no experiance can really grasp... its like your advertising poison, unless your the one who will teach them about it and answer all the potential questions that may come up...
For me it's pretty straightforward, and I'm relatively new at this. Grab an NZB, import into my client, check for errors, fix if necessary, unpack, and do whatever is to be done with it. On my connection the entire process is still several times faster than torrenting.

with all the automated usenet viewers, it doesn't seem much harder to use than torrents
