I was sent an email by a lady called Tina Sans, asking if I would be interested in re-posting this.
I know I haven’t done anything on here for about 2 weeks, but what with another project consuming my time and a bit of illness, there just hasn’t been the time.
I am always looking for guest contributors, so if you’re interested please email me at email@example.com
For now, follow the link above to the web page. Each of the 11 theories has a hyper-link giving you more details about each. I have a lot of interest in this sort of thing, so thanks to Tina for sending the link along to me.
