I agree... the more I searching I do on this (and other) sites, the more depressing it gets.
There was a ton of reference material on these sites that is potentially gone forever.
Folks who have hundreds of photos posted would have to either buy into PB to make them visible, or update the old posts using another host.
Then there are those members who are deceased...
In either event, those photos are pretty much gone forever.
Yet I continue to post using PB. Although I'm doing more direct uploads than I have in the past.
