Buy Feed Commander Pro

Why?
Because Feed Commander Pro removes the backlink to Feed Commander.com.

Annual Access This small recurring yearly fee provides you with access to the tool here on our servers, where you may run unlimited RSS feeds. With this fee, you are given the additional option of removing the backlink to our site as you configure each RSS feed for display. Price: $19.97

Remember, you can try this before you buy it by using the free version.

The only difference between the free version and a Pro version is that you have additional choices at the end, to either remove the backlink entirely, or to direct it wherever you like.
