My last post here -

I've decided to permanently leave this platform (my account will be deactivated by tomorrow) and I have also left all other social media and will not be returning. I also closed my website bookpagemaster.com. I plan to publish a few more articles in journals over next 6 months under my name but afterwards will no longer since I am legally changing my name and also moving address (I am preparing to sort out the move and a lot of other stuff). For legal and privacy reasons I will not go into why I am having to do this but it likely will involve the UK Protected Persons Service at some point.

"Talmadge, a professor of geology at the University of Utah, related that he had been on an island in the Great Salt Lake when he saw a rainbow twice the width of a normal bow, yet there was no rain present. He guessed that it had been caused by the oolitic sand..." (Wilk, 2013)
