I'm sorry Yvonne, but I think that's exactly what Linda means, you comment and get comments from friends, not because you like their artwork so much but because as you said yourself "But it's hard to not comment on images of friends, simply because you like them as a person". I personally think you should only comment on pieces you really like, friends or not or give helpful advices to help others improve their work, isn't that what commenting is meant for? Pieter
