He was last seen only 3 days ago, if I was you I wouldn't freak out much He has a life outside of the forum you know .-.
eh, probably busy with things in real life. plus, he keeps a close eye on current situations via skype from what I know so it's not like he's completely gone. oh yeah, and from what I remember, he had a tendency to disguise as a mob to hide the fact that he's online. but I dunno . :P
he died He has a job and stuff in real life, and since his job for the server isn't like that of a helper or mod, it doesn't demand for him to be on the forums or server all the time. Although he might not be as active as some of us wish he was, in the end, he gets the job done. So, yeah. He's busy with real life stuff, as lila said.
Well I only see Dao on the forums as Robynub1337. Last time I saw him in game he was in /v and accidentally typed in the normal chat. So Dao might be on all the time like Lila said... hiding from us. XD
He has a life outside of Minecraft, he's online now but like @Heatdude Da Waffle said, he doesn't have a forcing-demanding job like Helper, Mod or Mod+. Also, his IGN is Daorack, but his Forum name is: @RobyNub1337
Others pretty much said it all. My job is to administrate. Helper, Mod, and Mod+ job is to moderate things and put the administrative decisions to action. That said I have been around, but its at random. I'm not on all the time, no, but you never know when I'm lurking around the next corner. :P
