I like this suggestion a lot, and would like to take it one step further -- open shilling. For example, I'm a big Beyer fan, I could post in the open shilling/manufacturer forum about the new "Manufactory" site, and I could do so in there without worrying about being labelled as a street teamer, since I already am admitting to doing so, just by posting in the forum.
Would that be okay? Or do we only want "official" members of the company posting in that forum?
