| 85 | This normally finds new newsgroups by comparing the active groups the |
| 86 | servers have already reported with those Gnus already knows, either alive |
| 87 | or killed. |
| 88 | |
| 89 | When any of the following are true, `gnus-find-new-newsgroups' will instead |
| 90 | ask the servers (primary, secondary, and archive servers) to list new |
| 91 | groups since the last time it checked: |
| 92 | 1. This variable is `ask-server'. |
| 93 | 2. This variable is a list of select methods (see below). |
| 94 | 3. `gnus-read-active-file' is nil or `some'. |
| 95 | 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively. |

| 97 | Thus, if this variable is `ask-server' or a list of select methods or |
