Nothing particularly special from me. The name is just a combination of my real name and post office box number - which makes it easier to remember who I'm supposed to be logging in as.
Although they do say that 666 is the Devil's number, so I guess that 333 might make me look only half bad - which is about right...
The picture is just me relaxing on the verandah at home. It's re-usable on most forums, whether they're for reading, music, or just rambling on.
