Under Website Features in the Webinfo Checklist of a Kintera Thon event is a section entitled "Event Social Media".  Within this section of the setup is an area titled "Twitter".  Here are what each of the options under this area mean and how to configure them.

Twitter Widget Title: - This is the title that will appear above your organization's Twitter feed, and will also be the text that is clicked on to access the URL in the "Link to Profile" section.

Twitter Widget Script: - This is where the Widget code that you generate from Twitter for your organization's feed gets placed.  For instructions on creating that Widget Script, click here.
