I guess it would be a neat feture if we could add more users into my Lightroom Mobile account so anyone one on my Family could help me to do some work on LR Mobile. I usually import photos to LR Desktop then sync them to LR Mobile. I then use LR mobile to start rating, flaging photos.... So with this feature i could have some help from my wife for example and help doing that, adding comments, share thoughs, etc. And when i use LR Desktop all that info would help me to finish the job faster. As each person in my family have your own tablet or smartphone, i guess that this would be a nice feature for others too.
