Apologies to all for not posting anything for a while. I have made the decision to relaunch my blog under my own name, at a new address:
http://gwynethwesleyrolph.blogspot.co.uk/
This was largely because I have lost contact with most of the old brain stimulation, self-development, and memory training communities who knew me under the handle 7Sigma or SevenSigma. Most people who follow me online nowadays know me by my real name, rather than a forum handle, and I also wanted to take the blog in a more scientific direction.
I will leave the blog up, and its associated website sevensigma.info, and may post the occasional article if I feel that it belongs to the theme of this blog better.
May I wish everyone a Happy Christmas.
