I've just had an idea that I think is worth sharing!
I wouldn't normally say something like that, but this seems quite simple, elegant, and attractive!
What would people think of a third check box option to go with "I own" and "I want this set" against sets:
"I used to own"
It would address a small issue where reviews you've written are no longer visible if you get rid of a set and uncheck it as owned (or at least that used to happen a year or so ago).
But more than that it would add instant nostalgia to the site, especially when most AFOLs have gone through a dark ages and may well have a very different style of collection now, and would be able to see/tell/share their story through their collection.
It was just a little thought that popped into my head, and the more I thought the more it seemed like a really simple but really worthwhile idea.
I know I'd love to mark down all the pirate, castle and space sets I used to own, and I'd like to be able to be honest about some of the sets I've got rid of but still have my reviews visible, with reviewing being kind of a big part of what I think of as my input to Brickset.
What does everyone else think? Would you like it? Why? Is it as simple a thing as I think in terms of the database, programming, etc?
(I'm off on holiday tomorrow morning for almost a week now too, I wonder where this might have gone when I get back.)
