D'oh: I thought I was posting this in the cheats,hints,spoilers forum. Moderators might want to move this.

Try to make this as least-spoilerish as possible, but I need some help, just a gentle nudge in the right direction. . .

In Winterhold, there's a shopkeeper, you find outside her shop with her drunkard husband. She says she'll buy or sell almost anything, but actually, she won't offer to buy or sell anything. Is there something you have to do to get her to open her shop? She mentions something about a coral claw (I think she even gives it to you) if you choose one of the dialog options, but you never receive a quest in your journal (so I have no idea where to go to in order to complete that quest). Do you have to go clear that cavern and use the claw there, before she'll open shop?
