You know, I've read and re-read this thread (and the other two related threads). I've considered different ways of taking some of the comments and outright statements that have been made against (and in favour of) various contributors. There seems to be very little goodwill being shown (in any camp). I've lost all appetite for this project in the present circumstances. Regretfully, I'll now work out something on my own that could possibly be considered a F12. I hope you all have fun bickering among yourselves.
