I think that Redhorse has raised an interesting point:
The only other improvement I might offer is in the AU section. There are AUs that are quite intelligent in their premise, thoughtfully developed and possessing of their own high quality. There are artists there that work beyond the "cut and paste" or kitbash. There are several I check regularly to see what else they have done. (...) The admins and moderators may decide that some of these collections are worthy of retaining in their own subforum, but I understand the slippery slope this creates as SB acquires more quality artists every year.
IMHO indeed there are some AU's that are very much "worthy of preservation", also some stand-alone Personal Designs. Now, I don't suggest (and I believe neither is Redhorse) to post
all AU/PD content, merely few select ones, preferably only those "completed" or at least "already well developed" (so something more than "started impressively and then dropped").
P.S. On a note: current AU folder is partially unusable due to numer of damaged files.
