I normally use gnus-group-make-rss-group, G R <full RSS URL> RET to
subscribe to RSS feeds in Gnus.  The minibuffer prompts for a title, and
then the group is immediately visible in the *Group* buffer.  Can you do
write gnus-group-make-atom-group for nnatom, eliminating the server
browsing step?  (I didn't notice the *Gnus Browse Server* intermediate
before -- i.e. that I wasn't already subscribed and put back into the
*Group* buffer.)

Hmm, now I can't just paste in the full URL without an error being
thrown; I think removing http:// or https:// (if required) should be
done by automatically nnatom.el, for useability.

I tried the latest version against my blog's
https://www.fitzsim.org/blog/?feed=atom URL.  I can browse the group
fine, but after I subscribe to it, when I hit RET in the *Group* buffer
I get "Couldn't open server" in the minibuffer.  *Server* shows:

{nnatom:www.fitzsim.org/blog/?feed=atom} (opened)

This is still all only using one feed so far.  I will test multiple
after one feed works from *Group*.

Thanks,
