Deltafish spends a lot of time on IRC (joins #Nv2.0 rarely though). He generally goes by the name "Deltafish" and is a very active user when it comes to talking.
He tends to log on with two clients open. The second client's nick is usually Eeligon or Hooligon, but the name does vary.
Deltafish owns a channel called #TheNether which automatically ops anyone who joins. Unfortunately, the channel rarely gets visitors since the channel has no theme or purpose.
Deltafish is also savvy with IRC commands.
