I hate to give the Devil his due, but one of the features I really like in IPB 2.1 is the RSS Import System.
What it does is this. I define a newsfeed for a forum, how often to check it and how many new feed to process.
Every X hours, that feed is checked. For each new Y feed, a new topic is created in that forum.
This movie shows how its administered.
This one shows what the user experiences.
I would kill for something like this in vBulletin.
I'm willing to pay to help get this one started.
