I would say, yea...but it can happen. you cant remember every time if someone used full name or not. so it isnt that bad.
i usually name my full name when introducing. i dont like it too when someone just says the forname, or a short version of it, and than you see the full name
Something else I learnt yesterday about names, I learnt it from Danny (Y'know, that 12 years old sugar-high kid):
After a little discussion, Karl introduced himself, and he did too. I noticed he didn't #i, and asked him ((#i please)), then he told me it was a fake name.
Woah, great idea, never thought of that ^_^
My goblin needs a fake name.... would anyone go for a hyperactive cross stealing goblin named Jakob?
Or or... eeehhhh..... Alexander! Yes Alexander, perfect!
