I adopted the pseudonym 'johnlilburne' when I first began to post on the MLMB way back in 2006. I thought that was accepted practice or convention at the time.
I must have been interested in C War history at the time. I'd read the Brailsford and Hill's The World Turned Upside Down; then I read the Gregg. I also read H.V. Morton's The World of the Ranters. If I had my time over again I'd probably adopt the pseudonym 'Abiezer Coppe'.
I'm more into the philosophy of biology at the moment.
