I remember I was confused that there exists 'gnus-home-directory' as
well as 'gnus-directory' where both doc strings more or less say that
everything will be derived from them. I see now that in gnus.el
gnus-directory is set to gnus-home-directory (except when the SAVEDIR
environment variable is set...). In gnus-registry.el,
'gnus-dribble-directory' (which, granted, is usually nil) has precedence
over 'gnus-home-directory' for setting 'gnus-registry-cache-file'. OK, I
suppose I'm nitpicking here...

OK.

Yes. This setup 'evolved' before I became more familiar with elisp...

Since I guess I am only using ~10% of Gnus' functionality I wouldn't
know for sure. I guess syncing the registry file isn't really necessary?

Yes. I'll revise that page as soon as I have time. Thanks for your
comments.
