| 84 | This normally finds new newsgroups by comparing the active groups the | |

| 86 | or killed. | |
| 87 | ||
| 88 | When any of the following are true, gnus-find-new-newsgroups will instead | |
| 89 | ask the servers (primary, secondary, and archive servers) to list new | |

| 92 | 2. This variable is a list of select methods (see below). | |

| 94 | 4. A prefix argument is given to gnus-find-new-newsgroups interactively. | |
| 95 | ||
| 96 | Thus, if this variable is `ask-server' or a list of select methods or | |
