Well friend, if you read further into the forums, you would have seen where these quests are available. Now I'm not sure which one your refering to so, I'll just point both of them out:
1)
Bandits kidnap a girl. In this case, you speak with a merchant and he will give you some money to pay the bandits to let her go (or you could slaughter them all and still get the girl, that's what I do anyway). Be sure to have an available party slot!
2)
Capture an enemy nobleman. You get this quest after joining either the Vaegirs or the much better/cooler Swadians. After aligning yourself with either faction, talk to one of the count's or king and they will bestow this quest upon you. Just be sure you have some blunt weapons. Oh, and if you're wondering why you have never seen a nobleman wondering around, they only show up while the quest is active.
