Google just made an announcement about withdrawing the Files & Pages
features of Google Groups as they are offered in a better way
elsewhere in their portfolio. Thinking about it, this make more sense
that making Google Groups look like Yahoo.
See

for more information.
We are investigating alternative storage using Google Docs & Google
Sites, which look promising.
There is also positive news on the Yahoo! front - more anon.
Cheers
Moderators.
