Thank you very much for this info! I RTFM and STFA while I SMFB
(anyone care to guess what that is?) often, but have never gone
through Appendix Q. I very much appreciate that bit of insight, I am
sure that will save me a post sometime or later. Maybe someone (me?)
should consider writing a newbie-guide to TFM, with tips such as this.
Any one else has a tip that I should include?
