You have to ask yourself, is this really the right forum for this sort of discussion? Do you really want a moderator making a field call as to whether this violates this rule...
Because as long as there's no call on the field, there are no infractions. As soon as there's a call on the field, well a moderator has to do something about it.
It's up to you guys.
I think the mere mention of homebrew & what one could do with it is OK - it seems many Wii HB types are less about piracy/cheating than doing coolthings w/ a Wii that it normally cannot - the storage of game discs on an ext drive, for example - very cool, but also a way to pirate rented games.
I would think step by step instructions or link to such things might cross the line - besides, if someone really needs such info, they have Google.
But discussing some of the non-criminal HBC apps would be "safe", I assume.
