The Rbase list is now being archived on;
www.mail-archive.com
This is a free service which archives all email sent to the list
and also provides an email search function as well.
There are also instructions for moving any personal archives you
have to make them available for searching.
The MajorDomo program being used for the Rbase list on
sonetmail.com should also have a complete archive as well,
hmmm, now if we could get someone to move those as well, using
the available perl program you can download from there site we
would have a nice searchable email archive.
