Oops. Ignore this message, I messed up :P

Yeah RangerDown... I think that is the same sound that triggers at the completion of an adventure as well but can't remember offhand. Definitely different than the ding sound though.. :)

I agree that its not a crucial part of gameplay but whenever someone figures it out, post how ya did it... :P

give four orc belts to the captain in west freeport(in eqlive) and you can check it.

ok done,you can do it with quest::ding();
