Yeah! The folks at Moo have released a Lightroom plug in that makes it easier than ever to get photos to Moo.
Visit this page and grab the zip file – click the Zip button to get it.
Unzip the contents and rename the folder moo.lrplugin
Then launch Lightroom and choose File > Plug-in Manager and grab the plug in folder. That’s all you need to do. It will be installed and ready to be used.
Just select the images to send to Moo, choose Export and select the Moo Export Plug-in from the Lightroom Presets in the Export dialog.
