Presents the standard FeedBlitz subscription form for the list, including branding and custom fields as appropriate.
If the URL specified is not a feed, FeedBlitz will attempt to determine the appropriate feed from the autodiscovery information (if any) provided by the URL.
If no publisher ID is specified, FeedBlitz will attempt to match the URL with an existing publsiher account. If no appropriate publsiher account can be determined, a standalone (independent) subscription is created using FeedBlitz default branding.
If a publisher ID is specified, FeedBlitz will create the subscription and (if necessary) a new mailing list for the URL.
