Peter Jaworski does an excellent overview of the Windsor Liberty Seminar, and since I'm lazy, if you'd like to know more, reading his post on the day.
Contacting Peter is also a great way (in fact, it's the best way) to find out more about the Liberty Summer Seminar, which, in case I haven't hammered it into your brain enough, you should attend.
Blue Blogging Soapbox offers another thorough (and flattering) account of the seminar here.
Ian Clary, another WLS attendee, offers his thoughts on the seminar here , with hints at more thoughts on the day to come. Read Ian's blog for his thoughts on libertarianism and Christianity, a topic I always find quite interesting.
