Update: I somehow managed to write a hack to allow you to choose the RSS feed(s) you want via the list on the bottom of the
Edit Options section of the User CP. In other words, just select whichever feed you want, and it will be displayed on the your portal.
For server security and resource conservation purposes (caching a new RSS feed is a very resource intense process), you should suggest which feeds you want to be on the list. If you ask nicely, I may even be able to give you a completely custom, personal feed, e.g. something like "Low_Blow's 30 latest YouTube videos".
If you have absolutely no clue what RSS is, the
Wikipedia entry on RSS may prove a helpful read.
You can see examples of active RSS feeds on
Yahoo.
Again, start suggesting feeds!
