They are moving out of the cities in Excalibur now, one was shouting in Bentbranch yesterday while I was mining, and I kept on spelling his name wrong in my blist as it made no sense, and would scroll that fast and the message was that long I'd literally only have a second to see it before it was gone.
Click the name -> Send Tell -> Highlight name -> Ctrl+x -> blist add -> Ctrl+v -> Winrar

I click to send them a tell, put parenthesis around their name and change the /tell to /blist add
