Douglas Carnall, General practitioner E8 1AJ Send response to journal: Re: bmj obstructs science	I wanted to send a link to a friend about the letter I freely wrote you in a spirit "both friendly and scientific" but you have locked me out from my own work. This is my last contribution to your journal until you make it free again. You are not scientists, you are an obstacle to science. With regret D. Competing interests: None declared
