- "*Non-nil means that Gnus will run `gnus-find-new-newsgroups' at startup.
-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\")))
