I'm not a redhead in SL; SL is how I wish I were. In RL my hair is gray.
But in SL my hair can be gloriously, outrageously red. There's a flickr group for SL redheads, the very reasonably named Redheads of Second Life, and it has some glorious photos. Do give it a look.
(Of course, no discussion of redheads in SL could omit Codebastard Redgrave, photographer, scripter, and maximally callipygous resident of SL.)
So, RL redheads, know that I envy you, and I hope you don't begrudge my partaking of a bit of that aura in the virtual world. (Don't miss this collection of redhead history, legends, quotes, and images.)
