General RMC chat can be posted on any of the threads you think it would be most appropriate, what do you have in mind? To be honest most of the threads usually divert from the subject in hand eventually anyway so its not a problem

I think if the private members sales threads stay focused on the item being sold then that would be better however because it unfair to the seller otherwise. That said, feel free to post away and take it from there

What do other forum members think?
