This has been suggested over and over again but for whatever reason nothing has been done about it. Persoanlly I wouldn't mind even if they limited the amount of uploads to three per WEEK. It's not a solution to tell people to only look at some of the galleries... There are many people like me who like to view all kinds of artwork and browse the galleries using "All Galleries / What's New". I'd really like it if Renderosity limited the amount of uploads.
