Thanks Alex.
Something must have changed as the link I had been using (and working until last Friday) was
http://www.textadventures.co.uk/forum/feed.php
But now this seems to have changed to http://
forum.textadventures.co.uk/feed.php
The path
/forum is now part of the domain. ( I think that's what it is called)
Anyway, all sorted now and working again.
