Wow that is ambitious~!!!
I do however see a few things that could be difficult, however not impossible to overcome, I will add this however,
UPkeep on this would be a tremendous effort...
.as a few folks have mentioned these pins do not stay in trading long,the variance on actual scene content would be substantial, and the storage capacity for some of our more photo talented folks could be mind shattering,,,
,<ie I shoot almost all my pins with my phone, however folks like heyyouwannatrade<sorry sp, amanda> or others, photography is how they live so they have good equipment!!>
We try to have folks use links to outside storage spaces, to save our servers and memory for the lots of stuff that goes on in our community, check most of the more photo heavy threads and they will all be links, so now you have links to actually coordinate<I do not forsee the PTB granting that much storage for a single pin type for trade or sale,but I will post this thread to the mod/admin forum<yeah we gots one>
Lastly the maintence on this thread would be a real PIA, with each trade , links and discriptions would have to be deleted and then added for each new member whom aquires one to trade.
No offense, but that could be a rather intensive job,
all in of itself,,,,, 24 pins, approx<dont beat me pixie if the number is wrong>8 scenes per and of course oddities<AP, artist signed, etc,,,>, YOu are looking at approx 200+ catagories to list pics in.
And the discriptions would have to be at least standardized to allow for semi easy indexing<NOT every podm is a grail, just ask those with fireworks or horses butts>
Which of course will lead to some,errr,,ummm... discussion to say the least as to proper catagories or sub headers for each cell to be labeled under<not all have just "log scene from LK" or " Areil w/flounder " will satisfy each holder of the pins<becuz pin values are so subjective>
As I said I will mention it to the ptb, and while a marvelous idea,, I believe it will require a tad more effort than may have been anticipated by some of our members.
