Richard,
I am still scratching my head as to why my server alerted me on September 23rd to a post made in July.
Like everyone else, I check the box for strings in which I am interested and/or involved. I checked my email last night, got a new message regarding a string that had died out for which the last post was July 30th.
I am not nearly as sophisticated as you camera guys or those who place links within your posts. (I am a "querty meister" but I had to give up my blackberry when I moved to a dead zone). I don't know how or why this happened but it did.
Mystery.
