Quote - How far back do you realistically expect them to go? Back to Poser 4? 3? How far? Poser 4 is over 12 years old...

More to the point, Poser 5, which made the shift to png for thumbnails, was released 8 years ago.  Given that we had 4 versions and six years to convert rsr files before the format was finally made obsolete and support stopped, with some of those versions available for free for sometime now, and with multiple free conversion options available besides Poser...well, at what point do you say "deal with it"?
