Don't worry, I didn't consider your comment as too negative. And even if it was, it would have been a valuable feedback. For me (and I think my team-mates would agree), the comments we get are better feedback than any ratings. So we appreciate any comment - be it positive or negative or indifferent (that doesn't mean people should stop rating).
Sorry we didn't go for underwater archaeology this year. Atlantis is still good for another adventure, I guess ... ;-) (ek)
