After a binge of Outlaw Star, Reboot, Star Trek, and Babylon 5 I chose the username starwindsurfer, intending to evoke the image of solar sailing and stelar exploration. Instead people though I was really good at wind surfing, as in the water sport, something I have never done. So I found a Latin dictionary and came up with:
sidus : constellation, star.
no : (nare, navi) to swim, float, fly, sail.
So there you have it, I am SidusNare, the constellation swimmer, or the star floater.
