Thank you for the response thus far....one question keeps recurring about the formatting of submissions.
I will have to formulate an 'official' set of submission guidelines for The Transhumanist, but it is quite simple:
Please convert your essay into text format, paste it into an email and send it directly to me. Or, compose it as an email in the first place.
Please do not use attachments or send me to an URL to pick it up. The reason is that I operate out of two or three computers per day and need to be able to ship emails through different software systems.
