If you’re looking for more information, then you should be aware of the incredible list of resources that Tom has posted on the Lightroom Journal.
And if you have questions/suggestions/comments, please post them to the Lightroom 4 Beta Forum. There are a number of phenomenal community moderators as well as employees that actively participate in the discussions. (Including Victoria Bampton – who is truly the Lightroom Queen!)
Thank you to all who support us!
