Sadly it seems that Sellathon as well as Auctiva have disappeared from the face of the earth as well as from the web.
Yes the listings look terrible - yes the showcases have disappeared - Yes potential customers cannot see the other items NO NO NO contact is possible with any Auctiva or Sellathon links. It would certainly be advisable for both to have a secondary server to at least let people know what's happening and just how long the system is likely to be down. I CANNOT believe that they lack both the ability and the finance to move things along faster than they have - not a good advert for either service!
