This is an ID for Robin Zimmermann, the son of the initial author, and referred to as 'R' in the course of his 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.
