I sent the following letter to the site administrator on behalf of the
group.

Dear Sir

I see that you are imaging our discussion group on your website.

I have no problem with that, it is a public space, but would appreciate
it if you could clearly identify the source of your information so that
those of your readers who are interested, are empowered to participate
in the discussions.

There is an FAQ for the newsgroup at www.cancersupporters.com which
includes information about accessing the group.  Perhaps adding a
suitable reference to that would achieve what I ask.

It also would appear that you are claiming copyright over the content,
which is clearly not yours.
