Subscribing to a foreign group from the local spool is extremely easy, and might be useful, for instance, to speed up reading groups that contain very big articles—‘alt.binaries.pictures.furniture’, for instance.
Anyway, you just specify nnspool as the method
and "" (or anything else) as the address.
If you have access to a local spool, you should probably use
that as the native select method (see Finding the News).
It is normally faster than using an nntp select
method, but might not be. It depends. You just have to try to
find out what's best at your site.
