I've been reading these posts with a great deal of interest. I don't know what much of the fuss is about (having joined this forum about 2 years back), but I will say that I have had some VERY helpful responses from experts and beginners alike. For the most part this list does a great job in helping newbies. It would be a shame to change things. JMTC, Anjan
