i like graphics communities that are members only or closed community... like you said, this way you know who has been added and will be able to keep in touch. i agree about the credit. its not even that hard to do so! and i dont get people hotlinking. its sooo annoying.
That being said, is it okay if you add me? I am really interested in joining this community for all the amazing icons talented people make here.. and i promise to credit whenever i use them. =] Add please?
