Morrowind handles dialogue from the top down, and with greetings it starts at the first greeting in the "greeting 0" list, then if it fills the contitions for the first one, all the ones below that are ignored. If none of the "greeting 0" conditions are met it goes to "greeting 1" and repeats the progress. To make an NPC stand still, near the "dialogue" button is an "AI" button, delete the "AIwander" in there, save the AI options, save the NPC, open the NPC and the AI menu back up, add a new "AIwander" and set all the values to zero. In my opinion though, I think the actual prostitutes should wander, but the trainers and shopkeepers shouldn't, because if the prostitutes are wandering then more people will notice them, and thus use their "services". To see if somebody's dead, there's an example in vannilla morrowind, in the "my family" topic. I think. That one vampire quest with the vampire hunter. I hope I helped, even just a little bit. :) EDIT: To clarify on the dialogue: If the first thing at the top of "greeting 0" has no conditions, every NPC will say that every time you talk to them, because the things below are ignored, because the conditions are automatically considered to be met, even though there are no conditions. So never make a greeting with no conditions, even just make it NPC or faction specific, otherwise EVERYBODY will use that greeting. (If it's at the top of "greeting 0" that is.)
