Personally, I have always been a fan of the 1 for sale thread per username. But that is just me. Reply and/or edit your own thread as you see fit, but I do not see much point in a new thread every time.
As far as forum etiquette goes, there are two people who own this forum and their word IS the etiquette, and any commentary on what is proper etiquette is a waste of breath. They built a house and invited everyone to come party. And, they are remarkably tolerant about what they let go on in their house. When someone abused his power, they didn't ban him, but just took away his keg tap. Even when he stole money, they just put a scarlet letter on him but let him stay around if he wanted. Though that individual has chosen not to participate, that is his choice. From where I stand, any perceived favoritism is highly limited in the scope of that perception. Anyone who does not like the rules, or lack thereof, is free to leave at any time they want (right Ben?).
That is not to say they will not listen to suggestions, but it seems to me they have are crystal clear in their idea of how they want things to function. And receiving money from anyone in this community is tops on the list of shit that isn't going to happen.
