It seems to me then that the courteous and prudent  thing to do if the vendor (or a forum Admin for that matter) saw it would be to point them to Support, if nothing else to to prevent a refund request. Pasting in a boilerplate reply would take a few seconds. I've recommended to users here and elsewhere to file support tickets on Poser issues. 

However, this thread is about the shortcomings of the Rendo site...

Lol, yeah I do see your point. however the issue would be the time taken scouring the forums required to pick up any stray post relating to a single product and any missed may feel neglected anyways. Generally people go the forums with generalised issues as others may of encountered the same issue and have a solution readily available which is practical for them. Most DAZ3D customer are aware of the existing support systems and really don't need to be directed. As far as Rendo site shortcomings go, I'm really starting to wonder which is longest a piece of string or a thread relating to Renderosity site issues. Maybe Renderosity should consider some kind of bug reporting system, but I guess then the forums would be close to empty ;)
