I thought of a time limit, but don't you think 
people wouldn't bother to list and relist 
something they might have casually for sale 
(meaning, they're not dying to sell it, but if 
someone wants it that badly. . .) that didn't 
sell?

Maybe an automatic e-mail that comes once every 
couple weeks to one month: "Are these cels still 
for sale? If not, please delete them at this 
link: ___insert a link for them to use___" Or 
something of that nature. What do you think of 
that?

Of course, this is still all theory, but it's 
sounding really good. ^_^  I know I don't spend a 
lot of time hunting for sale pages on private 
sites. If they're listed on the Forum, I'll most 
likely visit, but otherwise. . . It really would 
be neat if there were a page like this. ^_^;
