Webinars are an awesome way to gain information fast. They are basically seminars over the internet.
If you've never attended a webinar, it's very easy. You register for an event, then you click a link at the appointed time to join the conference and you can also call a phone-line for the audio. You watch and listen to the information and you're able to ask questions online or in person if the session time allows. You will sometimes receive a recording of the session afterwards if you can't attend in person. (I will generally include a recording to people who register because of many timezone differences.)
