Hi, I know what you mean, I order and sell quite a lot on Discogs and though I mostly have good experiences, there's also some bad ones.
The problem with the different versions is often that if at the moment of listing an item, only one version exists on Discogs, people then list their sale item as that version, regardless of the version they own. If then later more versions get added, they don't change it anymore, either becaue they don't know a new version got added or because they're too lazy.
Personaly as a seller I find it kind of intimidating when a CD is listed in 30 different versions. You end up not knowing which one to order
Btw.: what user name do you use on Discogs ? Maybe we did business there in the past ?
