Right now until the 21st Yahoo is storing Attachments in the message
archives along with the messages that had them included. After the 21st
Yahoo will be removing the attachments before archiving. So if you
receive a message from the group and if it has an attachment save it to
your hardrive if its of interest to you because after the 21st you won't
be able to retreive it from the message archives [the message will be
there but the attached attachment won't].

see you all in a few days,
joseph
