|
||
This normally finds new newsgroups by comparing the active groups the
|
||
servers have already reported with those Gnus already knows, either alive
|
||
or killed.
|
||
|
||
When any of the following are true, `gnus-find-new-newsgroups' will instead
|
||
ask the servers (primary, secondary, and archive servers) to list new
|
||
groups since the last time it checked:
|
||
1. This variable is `ask-server'.
|
||
2. This variable is a list of select methods (see below).
|
||
3. `gnus-read-active-file' is nil or `some'.
|
||
4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
|
||
|
||
Thus, if this variable is `ask-server' or a list of select methods or
|
||
`gnus-read-active-file' is nil or `some', then the killed list is no
|
||
longer necessary, so you could safely set `gnus-save-killed-list' to nil.
|
||
|
||
This variable can be a list of select methods which Gnus will query with
|
||
the `ask-server' method in addition to the primary, secondary, and archive
|
||
servers.
|

Eg.

(setq gnus-check-new-newsgroups

'((nntp \"some.server\") (nntp \"other.server\")))
