A couple months ago I did a webinar on Designing with Sitefinity. It has now been posted to the Sitefinity web site:http://www.sitefinity.com/support/webinars.aspx
This was my first webinar, so be gentle. :) I said "uh" way too much. When I was rehearsing I was told "you're talking way too fast", so I over compensated and spoke way too slowly. *sigh*
Feedback is greatly appreciated. We have more webinars coming soon!
