How do you create a Twitter List Widget after change?

[Steven]

My Twitter list widget now doesnt show at all on my forum sidebar. It appears to be a change in the Twitter api? Ok so what's the deal, how do I create a new list widget for a forum sidebar that I can customize?

Log into Twitter’s developers section.
Go to “My Applications,” and click “Create a new application.”
Fill out the required fields, accept the rules of the road, and then click on the “Create your Twitter application” button. You will not need a callback URL for this app, so feel free to leave it blank.
Once the app has been created, click the “Create my access token” button.
