Add a directory in Godaddy's hosting
As I'm sure we've mentioned about 100 times, the only installation for adding Feed.Us to your site (any site! any platform! any server!) is just a directory and one local file.
Here's a 90 second video of how to add a directory in Godaddy's hosting. Godaddy is slightly confusing and has recently changed their hosting adminstration options. You'll need to find the "file manager" to add a directory. Then you'll have to add a "CachedWebContent" directory and give read and write permission/access.
This video takes you through it. Sorry about getting cut-off at the end. We're trying flickr video hosting and it cuts off at 90 seconds.
