Thank You for a Great Conference!

Another successful conference is in the history books. Great food, views, friendships, and ideas were enjoyed by all June 6th through 8th in Napa, California. This event brought a near-record number of user presentations. A special thank you goes out to Meredith Delk, John Sturges, Joe Mitchell, Sam Henderson, and Eric Gardner for sharing their experience and knowledge with the group. We also welcomed 15 first-time conference attendees and a new website and online forum.

The new website provides a clean and modern design optimized for a mobile experience, improved security, and many features that encourage greater online community. Existing users only need to reset their password to begin using the new features.

Remember to update your profile picture so that others will recognize you, then browse over nine years of past conversations, ask a new question, or share your feedback about the new website.
