Serendip's forums sometimes get longer than what can conveniently be accessed and displayed.  They are, at the same time, in their entirety an important part of what Serendip has become at any given time (and, of course, particular contributions may well be of lasting significance).  To try and balance needs for easy display and those of continuous and permanent record, only this year's forum comments are displayed on this page with earlier comments being preserved elsewhere.
