  There was a message a on October 18 that indicated
this list was
 going to be moving to the Shared Weight list server. It seemed to
 indicate that everything will be moving including the past messages.
 The messages posted up until October 28 will be available until December
 14. There may be a short gap in messages since supposedly none of those
 posted after the 28th will be stored. However, looking at the list
 website I see this message I'm replying to listed, so perhaps new
 messages will continue to be stored until December 14.

1. The full info from Yahoo! is that they are effectively changing the 
Groups to be more like Mailing Lists.
As such they will continue to provide a service of that nature for 
however long it is Yahoo!'s pleasure to do so, certainly past the 
December date listed.
"Content" refers mainly to that held and viewed at a Groups's web page, 
and it's Files, Photos, Database areas. This is what may not be added to 
now.
It's all there to read on various Yahoo! pages.
2. I hope and expect that when this list is hosted at Shared Weight the 
archives (which include messages posted a few minutes ago) of it remain 
not visible to public, and search engines, as it is now.
To move to an open model, as existing Shared Weight lists are, without 
stating such a change is occurring would be very poor form.
To make messages passed around (shared) on the Yahoo! Group Trad Callers 
suddenly visible would similarly be poor.
Whether there is sensitive material, that was shared in this group's 
environment or not, it is a change. It is more than the principle of the 
matter. There may have been former members/subscribers who would not 
appreciate such an action.
Should it come to be an open archive it would be appropriate to keep 
messages from the period of this Yahoo! Group prior to being hosted at 
SW in an archive requiring membership in the successor list to view.
Cheers, John
