Evebtually found this on Wanadoo's site:
"Our Newsgroups service now closed
Article ID: kb6721
From 17th March 2006, we will no longer provide a Usenet/Newsgroups
feed. Although we cannot ourselves recommend an alternative
Usenet/Newsgroups service, the following is a brief list of operators
recommended by newsgroup viewers and contributors:
http://www.giganews.com/
http://www.easynews.com/"
Both of these are paid for services but it was included in the price
from Wanadoo.
This was done without warning and I'm now looking for a UK ISP which
will allow me access to newsgroups, including binaries, any suggestions?
