I often try to comment and can't because of Yuku. I try and try then give up. Then I forget to try again later. I love looking at peoples creations and no how much I apreciate it when they have taken the time to comment on mine.
Even a smile means they have taken the time and like what they have seen.
Maybe they don't like what they see and don't comment incase they offend. Maybe it's a time thing or they just don't want to join in! Who no's. Each to their own!
