I have a lot of sympathy with Newbie_Renderers position and share it to some extent.  I must say though that for me there are times when I don't feel that I need to add information to the image, the work speaks for itself.  I do try to comment on all those images that catch my eye without regard to who posted them but I'm sure that like many of you I miss worthy images on a daily basis. 

I'm lucky and have a broadband connection but I have a friend who contributes to Renderosity regularly but who only has access through a dial-up connection due to financial considerations and cannot play as full a part in the community as they would like.  I'm sure that there are many in the same position it's just unfortunate that we cannot tell who is and is not in that position.
