Just a quick Q. I have a dialogue branch where a NPC introduces herself and I wonder if it is possible for the player to respond "My name is [player name]" I'm guessing it would require either a form and/or scripting as the player's name is stored in a string.

I don't know how to do it, but it should be possible as letters are addressed to my characters by name, the Thalmor and DB refer to them by name and conjured creatures say 's Spirit Wolf etc.
