Just a question.

I'm not exactly 'new' since I've had five characters so far and learnt a lot, but I've never actually been able to communicate with any of the NPC's by using 'ask', especially rthe ones guarding doors that I want to know what's through them, or people like the bankers and lenders.

"ask" isn't usually the keyword.

You'll want to try "discuss <npc> topics" or "discuss <npc> name" to get them going.  "talk <npc> topics" (& etc) also works.  

Keep in mind that not every npc has been programmed with a talk script so you may still run into instances where you can't talk to one.  Bartenders are a good bet, though.

Ah thank you, I got a little frustrated with it haha. Especially with these people guarding interesting entrances and just looking at me blankly as I try and communicate with them.
