Yeah, I saw that e-mail as well last night and was saddened by it. I didn't buy much from her, but, I know there were several who did and it was a great way to get artwork from those series.
I'm surprised that the site was as active as it was for so long. It seems like more and more animation companies only want to release their artwork to collectors if they are the ones making a profit from it, and anyone infringing on that is viewed as competition.
