Lots of interesting stuff from him on this forum and AA, but it looks like his posts on AA stopped at the end of the 2014, and a bit earlier on this forum (although it looks like he logged into this forum in 2017). His old website is still partially accessible using "Wayback Machine", but not all of it - a lot of the visuals are missing.
Anyone know if he still posting/publishing somewhere?
cheers and thanks, Derek
