1. Go thee unto:
<
https://groups.google.com>
2. Near the top of the page, you should see a box with "My groups" on
the left, near the magnifying glass icon.
3. In this box, click on the tiny down arrow and select "All groups
and messages".
4. The nearly invisible light gray lettering on a slightly darker
gray background in this box will invite you to "Search all groups and
messages". It doesn't actually search all messages, but don't let
that bother you. Inscribe in the box "Dachshund" and hit <Enter>.
5. Just below the gray box, Google Groups will provide 3 of groups
containing "dachshund" in the name, followed by "+ 73 others". Click
on the "+ 73 others" and you should see 75 Google Group that involve
dachshunds.
When I tried the above, I was logged in with my Google account. When
I log out of all my Google accounts, going to:
<
https://groups.google.com>
results in Google demanding that I login or obtain an account. Are
you logged in with a Google account?
