Web Services has just release an enhancement to the List Builder that allows for RSS aggregation.
How does it work?
1) Simply create a list in the List Builder.
2) Go to the “Data Source” tab.
3) Add as many RSS feeds as you want.
Now just use one of the RSS feeds found on the “RSS” tab. We sort the items based on each item’s published date.
Let us know if you run into any issues.
