With Google Groups severing its connection to Usenet today[*], newsgroup
access will require what today are quite specialised tools; and even
before that (and before the recent spam floods, which will hopefully now
cease) they didn't seem super useful as a way of getting PuTTY support.

I've just removed the whole section, since we couldn't think of an
obvious consensus replacement venue -- certainly not one where we hang
out ourselves. There's Stackmumble and places like that, but we didn't
think of anywhere concrete to point to.
This has led to some rather unsatisfactorily vague 'seek help from some
public forum' wording in places, which could perhaps use revision.
