I wanted to post something similar to this a few days back but a technical glitch prevented the post to go live. I was more for a thumbnail system that clearly shows you what software it is for (or in the guise of a small letter like the R, B etc underneath the thumbnails). I am a Poser user but I regularly convert DS only stuff for use within Poser by either creating the Poser companion files from within DS or by exporting the OBJ files. A surprising amount of stuff can be used this way and I wouldn't want to miss these.
