Apologies for the long (several weeks) silence. I have been having some health problems, so my projects have not progressed in this time. I have to go for a scan this week, and hope to be back on track with the project next week.
Thanks to all those who have expressed interest in the project and have contacted me. If anyone has suggestions or feature requests (like extensions to the vocabulary), please make a post of the forum as this allows me to keep track of thinks.
