I originally wanted my username to be Orthodoxyproxy, I was interested in Eastern Christianity at the time and wanted to incorporate that within my profile. Looking back "0th0d0xypr0xy" is missing an 'r' and looks slightly silly.
Hope someone can provide the answer.
That's funny. I never noticed until just now.
Look in your account settings I believe
Nope, I don't believe I can. My username doesn't appear alterable. I'm left looking like a wazzok lol
