In the Adobe User 2 User forums, problems, feature requests and bug requests are often repeated as posts go to the 2nd page. In order to help with ranking and access Adobe have created a new feedback channel called GetSatisfaction. It’s online at http://feedback.adobe.com.
Of course this is a Lightroom based blog, so here the direct link to the Lightroom Feedback page: http://feedback.photoshop.com/photoshop_family/products/photoshop_family_photoshop_lightroom
To get started, sign in with your Adobe ID (or register) and click ‘Start a New Topic’. From there choose an option that fits the topic from Ask a Question, Share an Idea, Report a Problem and Give Praise. Fill in the text box, optionally including an image. Give it a title, and tick the relevant program box and the click ‘Post’. Follow the advice about tagging etc to give your post better chances at being seen.
