I want to store article bodies on disk, too. How to do it?
You can tell the agent to automatically fetch the bodies of articles which fulfill certain predicates, this is done in a special buffer which can be reached by saying ‘J c’ in group buffer. Please refer to the documentation for information which predicates are possible and how exactly to do it.
Further on you can tell the agent manually which articles to store on disk. There are two ways to do this: Number one: In the summary buffer, process mark a set of articles that shall be stored in the agent by saying ‘#’ with point over the article and then type ‘J s’. The other possibility is to set, again in the summary buffer, downloadable (%) marks for the articles you want by typing ‘@’ with point over the article and then typing ‘J u’. What's the difference? Well, process marks are erased as soon as you exit the summary buffer while downloadable marks are permanent. You can actually set downloadable marks in several groups then use fetch session ('J s' in the GROUP buffer) to fetch all of those articles. The only downside is that fetch session also fetches all of the headers for every selected group on an agentized server. Depending on the volume of headers, the initial fetch session could take hours.
