Oddly, the RSS feed works and I can get the feed to post into the forum, but I have to keep resetting the scheduled time and running the scheduled task manually in order for it to post into the forum. I have no idea why this should be. I have it set to check every 10-minutes. When I checked it today, it hadn't run in a few days. So, really, I'm still puzzled over the behavior of this RSS thing in vBulletin.
