I have fetched the Helm of Winterhold about thrice now in an attempt to become the Thane of Winterhold.. I am unable to ask the Jarl of Wintherhold 'Is there anything else I can do for you Jarl?' . I am level 39, I also enjoy the position of being Arch-Mage at the college of Wintherhold having completed that story line.
I have completed helping three people in the following way (I wasn't yet asked to help people by the Jarl though):-
&--#62;Give http://elderscrolls.wikia.com/wiki/Ranmir at http://elderscrolls.wikia.com/wiki/The_Frozen_Hearth Inn a drink, either Ale or Mead
&--#62;Drop any piece of Apparel from player's Inventory inside http://elderscrolls.wikia.com/wiki/The_Frozen_Hearth inn and let someone pick it up, (it is likely that the piece will not actually be taken and can be picked up later).
&--#62;Steal http://elderscrolls.wikia.com/wiki/Nelacar_(Skyrim)'s staff for http://elderscrolls.wikia.com/wiki/Malur_Seloth
EDIT: I am Thane of Whiterun, Falkreath, Morthal and Dawnstar and I have currently asked Valdimar from Falkreath (I think) to return to the halls of Jarl in his town. I am still at the phase of 'The Silver Hand' in companions quest.
EDIT : I have checked in my Chest where I store all the loot, and I have the Blade of Winterhold in there. Does it mean that I am the Thane of WInterhold already, If so how can I avail a house carl from winterhold ? I have Valdimar waiting for me in Morthal, do I hand him over to Delphine ? He doesn't seem to be as good as Rayya or Mjoll.
Can you please help me out?
Thanks in advance
