Thanks for all the info. I really appreciate it. I've been so busy with Christmas and all that I haven't had time for checking in with the responses. I hadn't realized that what I was being asked to do was a tried and tested method and that is the most important thing I could learn right now.

Thanks for the point of humor, Gargoyle. I hadn't realized what a sacrifice the Guamanians had made. They are so modest they don't talk of it themselves.
