So I'm giving The Elder Scrolls Online beta a try and I figured out how to join an ad hoc group. But I can't figure out how to share quests with that group. When I bring up my quests (J key) and then click on one, there is a Share option (F key). However, clicking on it doesn't seem to do anything and the others in my group can't join me in the quest.
So how can I share quests?
