People can call me anything I dont mind......but....if someone calls me "dude" I will deploy my hardpoints. I never have been, or ever will be a "dude". Grumpy old git, yes, miserable old B*stard, yes, but not dude.
I keep finding people using far too many words to say Hello to others in-game or being far too formal.
So how about "Hoi"
If you want really want to type in "Greetings CMDR" then keep doing it.
