I first registered with my first name. Things were difficult for me at the time and I didn't care about anonymity. But when I tried to post I couldn't because I felt too exposed. So I had to come up with something and it took a while. I was I wanted nothing negative sounding. I wanted something easy to search for with Google. (that's another story) So I came up with Candu because I can do this. (recovery) It took a month before I was able to get the name changed.
