Hello,
I posted many cels from Tenchi Muyo on auction,
here on animanga. They include many Ryoko (OVA, 
movie, TV), Zero Ryoko and Achika.

The URL is : http://www.animanga.com/db/auction

I also made some changes to the auction software,
including :

- Browse items with pictures
- Auction length is now reseted to 10 mins if
  someone bid during the last 10 mins. (Like on
  Yahoo)
- Improved checks when submiting new auctions
- Some various minor bug fixes.

Cheers,
Yann Stettler
