For Sale / Trade - [H]ard|Forum
I know this would be high hopes to see TF have classifieds like Hard forum, since that's pretty much THE Classifieds forum for Computer related products, mainly uses Heatware as their "iTrader" like system, which I wouldn't mind using, but don't really feel the need to, unless TF members start using it more, and feel comfortable with that.

Uses iTrader, here I usually get stuff sold rather quickly, if I push towards it.
Car Audio Classifieds - Buy, Sell and Trade Car Audio Equipment
Dedicated to classifieds, so of course this would be a little more intuitive towards classifieds sections.
Mainly random forums that I frequent, such as car forums, and audio forums. Even with the lower amount of people frequenting a few of the other forums that I didn't post, things usually get sold there.
