Excellent suggestion...without documentation most photos mean nothing.

Ever find an old family photo and wonder who the heck those people are?

I especially like citing the thread idea...contact information changes
but Usenet is the closest thing we have to archiving data that other
can access years later. I find myself reading threads many years old
for information. One of THE reasons why people should allow their
comments to remain....a fragmented discussion thread does no one any
good.
