1515 - * blog at the time -- usually meaning no user at all. But if WordPress
1516 - * gets a wp_insert_post() when current_user_can('unfiltered_html') is
1517 - * false, it will run the content of the post through a kses function
1518 - * that strips out lots of HTML tags -- notably <object> and some others.
1519 - * This causes problems for syndicating (for example) feeds that contain
1520 - * YouTube videos. It also produces an unexpected asymmetry between
1521 - * automatically-initiated updates and updates initiated manually from
1522 - * the WordPress Dashboard (which are usually initiated under the
1523 - * credentials of a logged-in admin, and so don't get run through the
1524 - * kses function). So, to avoid the whole mess, what we do here is
1525 - * just forcibly disable the kses munging for a single syndicated post,
1526 - * by restoring the contents of the `post_content` field.
1636 + * Postcondition: If $rss is the URL of a feed not yet on FWP's list of

1638 + * as its initial title and $uri as its initial homepage URL (normally
1639 + * these will be updated with new values taken from the feed, the first
1640 + * time the new feed is checked for syndicated content, unless feed
1641 + * settings prevent this). If $rss is the URL of a feed that is already
1642 + * on FWP's list of subscribed feeds, then that feed will be updated to
1643 + * use the title provided in $name and the homepage URL in $uri
1527 1644 *
1528 - * @param string $content The content of the post, after other filters have gotten to it
1529 - * @return string The original content of the post, before other filters had a chance to munge it.
1645 + * @param string $name The human-readable title of the feed (for example, "Rad Geek People's Daily")
1646 + * @param string $uri The URI for the human-readable homepage associated with the feed (for example, <http://radgeek.com/>)
1647 + * @param string $rss The URI for the feed itself (for example, <http://radgeek.com/feed/>)
1648 + *
