Hello
Would it be possible to have notifications show up if somebody replies to your comment or adds new comment to somebody else's picture you have commented earlier? (you get notifications if somebody comments _your_ pics)
Sometimes there are questions / short discussions that are easy to miss. Similar to Facebook where you are notified if there are other comments on items you have commented earlier?
Or is it intended that you subscribe to each picture (that is not yours) you want to follow for possible discussion and comments?
