This is an ID for Robin Zimmermann, a child of the initial author, and referred to as 'R' in the course of TopicPersonalHistory pages. The name was first invented when I was just returning from somewhere with somebody (possibly G), and I wanted some alliterative nickname (My brother and sister both had ones, so ... ). Mom suggested the word 'Radical', so I prefixed it to my name. The current incarnation is the shortened version.
