SEO Improvement for Webinars and Webcasts

To improve "search engine optimization" or SEO for webcasts and webinars, today we changed the URL structure of the enhanced web event listings that are uploaded by users to EventSpan. Previously we had a a unique URL for each event composed of a string of random characters. Now, with the new and improved URLs, we are using the title's words of the event, separated by hyphens, in the URL of the event listing. Using hyphens over underscores is better for SEO, as search engines like Google see hyphens as dividers in URLs and body text, and ignore underscores (underscore is not considered as a divider by Google).
