I originally chose to use the wordpress theme, zbench, its wordpress.org page is here…..
I moved the blog and changed the url from a sub domain to a page in a wordpress instance i.e. http://davelevy.info/blog and changed the theme to spacious.
I have moved my comments on the customisation of zbench to comments on this page.
I added the Related Post plugin in June 2013, and upgraded it to Jetpack in the summer of 2018.
I added artiss code embed in Oct 2013, see Embedding Code in WordPress, I still use this.
