Hi J. C. Rigg, welcome to Wikipedia! Your signature has not appeared on the comments you wrote on a couple of article talkpages- I think it might be because your keyboard is outputting the wrong character instead of a tilde. Hope this is helpful. Ning-ning ( talk) 21:46, 14 February 2010 (UTC) Thank you, I will sign in future 'Christopher Rigg' by hand!
