currently subscribed to those 5 (news.*) but not to any others on list;
also subscribed to about two dozen other newsgroups not on sample list,
most of which are low traffic/special interest groups; novabbs carries
this: https://news.novabbs.org/computers/thread.php?group=news.groups

if more websites (https://rocksolid.sybershock.com/rocksolid/index.php
for example) offered the rocksolid format, they could include whatever
newsgroups from any servers of their choosing; it's very user-friendly:
