Would you please provide more detailed instructions?  I don't use
Gnus, so after typing "M-x gnus RET" I'm lost.  How do I "open a
newsgroup"?  I tried subscribing to this group from the menu bar, but
I couldn't open that group after subscribing.  I guess I didn't select
a correct server or something?

Thanks.
