Zaudragon, you'll have to change the keyword to be compatible with the new /keyword behavior.
(I've been using this script for a while now, and it is indispensable!)

La, you put %_rss anywhere you can type text: messages, away/status messages, user profiles, and probably display names, though I don't use MSN.

Actually no, because Adium only updates info from its scripts ever 30 seconds. So I could update headlines more often, but that would just mean Adium itself would skip some.

Macaddct1984 - It actually cycles through the headlines at the interval you specify in the app. So if you have it set for 5 minutes, it would show the top headline for 5 minutes, then the 2nd headline for 5 minutes, etc. As for displaying more than one headline simultainiously, there is no was to do this currently.
Perhaps if I get bored at some point down the line... :)

Be sure you install the XML Scripting Addition, as described in the directions above. ;)
