I would just be happy if the people selling games in the for sale forum followed the rules and put their location in the title (you know like the forum rules REQUIRE). Would it be possible for the moderators to start enforcing that? A lot of very frequent sellers simply refuse to do it and it makes looking for machines much, much harder.
The games listed for sale in VAPS itself probably isn't that accurate, many people don't update their listing very often, and I have a suspicion that most of the games listed for sale on VAPS are not really actively for sale so much as they fall into the category of "I would sell this".
