I would like to make a suggestion : When I make a comment on an another artists  drawing sometimes the artist or some other commenter will make a reply. Right now there is no way to know if someone commented on what you said in another persons gallery. I know that sometimes when I come in I comment on  a lot of drawings so I have no way of tracking if someone replied to my comments without going back through and looking again which to me is to time consuming. But I would love the interaction with other artists. I think the ability to do this would bring artist on this site together more and You might see more interaction on comments. It might be a simple as connecting the user or commenter and sending a notification to the email box that there was a reply to one of your comments. Or in community forum to have the ability to do a search on your name to see the comments you made and looking over the list for any reply's .. Maybe others might have a better way of doing this?
