Tip: Visit kill collectors in lowbie zones.
I was passing through Ekrund lastnight and the Kill Collector for Snotlings at the Redhammer in was lit up like a quest hand in. Spoke to him and he gave me 3000xp or so for snotling kills, that I know I havent done in that area. Killed plenty in Gunbad mind you!
So it maybe worth visiting these guys anew and seeing if they are lit up for you too.
