Exporting to plaintext for FWN

Hi all, Two questions concerning the method by which Fedora Weekly News is turned from a wikipage into plaintext for email purposes: 1. If we use external wikilinks (such as [http://someurl.com Some URL] in what format will these be rendered during export to plaintext? 2. How/where is the plaintext generated? If someone can point me to appropriate reading material on this then I'd be grateful. I Googled around for information on general MediaWiki exporting and only found information about XML exporting. A brief search of the last 5 months of this mailing list's archives also revealed nothing. Thanks for any assistance, Oisin Feeley
