Before final conclusions are posted and this thread begins its inevitable slide into dormancy, I would like to tell you what a privilege its been to watch those of you with analytical or scientific interests and/or skills participating in this thread. Of course I'm impressed by your knowledge, but that's not what has kept me here following along with you through 1,300 posts, hundreds of which were mostly dry, scientific data.
I've stayed here for the long haul because it's been a pleasure to witness your determination, your resourcefulness, and most of all, your interactions with each other...your cheerful willingness to collaborate, to acknowledge your own mistakes without rancor, to give generous credit when due, and to graciously reply to questions from those with much less knowledge.
Threads like this naturally elevate Websleuths above its counterparts, but it's WS's members whose kindness, humanity, and restraint have created an overall atmosphere that makes it a pleasure, and a privilege, to belong.
