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.
