Don't give too much weight to my single experience. I've only been there for a couple days, and my questions were answered by the ruler at some length. I just expected a bit more of an initial greeting.
Lol you expect to much, If I am greeted I try to say hi especially if it's a occ from someone i've played with before. Beside that I make my own announcement or mark at some point within 1-10 days of playing or I stay silent because I am plotting something truly evil
