I'm pretty much sure that all quests that are available isn't listed on the wiki.
I would like to ask help from you and show us some quests that aren't listed here.
http://www.fonline-reloaded.net/wiki/index.php?title=QuestsMyself, I did find one at Redding Kokoweef mine building.
When talking to girl at building and ask about job, she offer you job to kill some rats.
First you need go talk man at Saloon, he does give you job to get 5 scorpion tails. Return to man and give tails to him.
And now return to girl and get your reward (you didn't have to kill rats, they only wanted scorpion tails in the end..)
100caps, no experience reward.
