As Mary has recommended it is always worth checking the Archives on this mailing list. Usually a lot of subjects have been covered and I remember something about this some time ago now. The Archives are very useful in that some questions may have been nswered - in detail - or websites given. I have posted a number of websites of interest on the list as well.
