Due to user demand, we are going to post a lengthy document filled with legalese here as soon as it is ready. In the meantime, you should understand that although you are allowed to create Feedpass pages for ANY feed URL, you must use the original feed URL to create your Feedpass.
The FeedBurner service (it's a different company) has flaws that allow you to "burn" your own feed using anyone's feed URL. We do not condone this practice and remind you that it is against FeedBurner's own Terms of Service. If we are notified of such use of stolen content in a Feedpass, we will remove the offending Feedpass page immediately and take action as required.
Any questions or comments should be directed to: firstname.lastname@example.org.
