This was posted in the Gargamel forum but I figured more people would see it here. Chris Kohler has created a wiki site for us to use at http://www.sofubi.com. It's pretty empty at the moment but it looks like it could be a really great tool for us collectors if it catches on. There is some discussion in the other thread about licensing for photos, so if any photographers can give permission for the community to use their stuff that would be great too.
I added an entry for the killer figure. http://www.sofubi.com/index.php/Killer does that formatting look ok?
It's a great start. Some additional useful information would be - name in katakana - size - original price - production numbers (if available) - variants And pictures, of course. I'm sure you could go straight to the source and consult with Mr. Spoons for a lot of this info.
