Well, well! I must be doing something right. All this controversy I've generated! I guess now I'll have to start my own competition. OK, here you go: post a reply saying which one you think I am, and WHY. Once I get sufficiently bored with reading all your laughable answers, I'll reveal all.
Just to keep it interesting, the winner (judged by me completely arbitrarily and not necessarily because they're right) will receive a pen. Might as well keep to the noble RinkWorks standard for prizes. In this case I will send the lucky one a genuine RNZ Coastguard pen, which will be personally swiped by me from the reception desk when nobody is looking. If I can't pull this off, you can have a bumper sticker instead.
Just to narrow down the possibilities, I am definitely either male or female, my biology coincides with my mental view of myself, I am straight, and I am not involved in any weird aspects of gender identity. So there you are, go for it. Of course, if the majority of people get it wrong for what seem to be good reasons, I will probably have a personal crisis and wonder what I'm doing wrong.
