This wizard will configure a news gateway: your server will be able to fetch newsgroups from an external news server (usually, the one of your service provider) and make them visible to your internal network. Therefore, the first step is to specify which external news server you want to use, as shown in figure 15-22.
Then you need to specify the interval (in hours) between every refresh (figure 15-23). Do not specify a too high interval: news evolve rapidly, as pretty much everything else on the Internet for that matter...
