Great question, and my handle, like so much else in my life is a combination of events. I go by Verb, which you'd think was unique enough to use, but it seemed like it was always already in use, apparently by someone named Verbosky, so I reversed it (Brev) to see how I liked it. That then reminded me of the old military brevet ranks and, as a cyclist, long distance rides,so I chose Brevet, which was also too common, so I appended the 05 to use the same handle on most sites. Wordy, but true.
