@eccles45. Here is one.
http://www.scots-online.org/dictionary/ There is a better one, but my link is on a different PC. You will probably find it using Google anyway. It has a Tam o Shanter icon when you save it to your desktop. IMHO there are too many (uninteresting) Scottish references in Mephisto, and I also think it has been 'dumbed down' over the last few years. A Dean Meyer ST Puzzle is often more challenging. He is looking like a successor to the late great monkey puzzler (R.I.P) in 'The Guardian'. ST will be lucky to keep him (or her if it is a pseudonym).
