Your very welcome Gram.,glad to see my post has helped a few(bigtim doesnt like my posts)lol.It would take awhile for me to search for exact names and turn-in points,however just go to factions left side of this page.then click on the faction and it will tell you specifics,however when you hit each town as listed above the person who gives you quest is the turn-in person.And repeatable quests put a blue question mark over the NPC's head.Still working on Cen. Exp. rep wish I would have known about the Unid. plant parts.Good luck man and have fun!

Thanks so much, jacknthabox.  You've helped me as well.  I'm lvl 65, LW lever 340.  I've been pretty much neglecting the rep farming.  From what you say, it sounds like this would have gotten me in trouble down the line.
