A Dinker is a common colloquial term (although some may argue that it has become 'official') within The Dink Network used to describe someone who plays D-Mods, follows new releases and updates, and contributes to discussions in the Dink Network Forums.
Though some Dinkers will argue that "Once a Dinker, always a Dinker", a Dinker is generally considered to be an active contributor to the community.
