hello, yeah I"ve got JB. But I think in order to use the custom RSS feature you have to have the expansion pack installed. then all you do is like add the feeds you want to the little text file named "anything.jb_rss" and toss that in your windows directory. Theres more instructions here at this link.

How do I add custom RSS news feeds?
Custom RSS feeds can only be added with the Journal Bar Expansion Pack installed and detected. See Why isn't the Expansion Pack being detected? if the Expansion Pack isn't shown as detected in the Journal Bar options page (the "General" tab).
Create a text file on your PC and rename it as a ".jb_rss" file (e.g. "news.jb_rss"). Each RSS news feed will have three parameters associated with it:
<title>Washington Post Top News</title>
<icid>5</icid>
<url>http://www.washingtonpost.com/wp-srv/topnews/rssheadlines.xml</url>
The <title> tags specify the readable name for this RSS news feed.
The <icid> tags specify the small icon (which appears in the top left hand corner of the Journal Bar page). Examples to set this to: 5 is the US flag. 8 is a globe icon, 10 is a home icon.
The <url> tag will contain the URL the RSS news feed is located at.
Up to 100 RSS news feeds can be added to the same .jb_rss file.
For a sample file containing some sample RSS feeds, download it here.
The file should be copied to your Pocket PC's \windows folder. Once this has been done, dock the Pocket PC then go into the Journal Bar Options screen and tap the "Update Format" button. Tap OK to cancel the Options page and go back to the today screen. Wait for Journal Bar to update the first weather section, then go back into the Journal Bar Options page and the new RSS news feeds should appear as available news feeds on the "News" tab.
