I guess the value lies if there are issues with a classifieds sale as it preserves the details of the advertised goods etc.
People are welcome to bump their threads up the forum by adding posts detailing price reductions etc.
Wetpixel's search functions are really good, and if you are looking for a specific item I would suggest that this is the most efficient workflow! Scrolling through any thread will result in a vast amount of info that is not relevant to your particular interest. The searchable forum is what makes accessing info here on Wetpixel so easy!
I will look into Fred Miranda's forums too.
All the best
