The BPP_CrawlLine plugin has a separate set of settings to work with RSS-feed.

"Time" – if RSS-feed has date/time of publishing, then the hour and minute of publishing will be added to crawling line.

"Header" – the crawling line will contain the header of RSS-message.

"Message" – the crowling line will contain the RSS-message itself. If RSS-message is absent or contains only HTML-tags, then instead of message only it's header will be displayed.

"Autoupdate" – set the frequency of updating of crawling line. After the set period of time plugin will load RSS-feed and automatically will restart crawling line. If the value of "Autoupdate" is zero, then automatic update is disabled.

"Latest news" – crawling line will contain only new messages, published during the time from the last start of crawling line. Time of last viewed message is saved by the plugin only for the current RSS-feed. After the change of link to the RSS-feed the date/time of last message is cleared.
