If you contact Lotus Notes ask them if they have an applet that works with the LCD manager for there mail.
If they do it may require you to have administrator access to turn on the feature i havent used Lotus notes in 10 years and i know it has changed alot since i last used the application.
To add a rss feed open the LCD manager
Click programs
Make sure rss feeds are enabled on both sides for the applet and 3dconexion
Click on rss feed
Click configure
Click new
add the rss web address of the website
example:
http://twitter.com/statuses/user_timeline/46142925.rss
push ok
Check with the website some require a signup before sending you to the link for the rss feed.
They also provide instructions and tell you to copy the link etc.
