I recently started using deviantART again after a rather long hiatus and it seems that the Linux community on it has grown considerably.
These days it has user-groups for a variety of desktop environments, window managers, and miscellaneous Linux-orientated projects.
However, I discovered that deviantART surprisingly lacked a KDE-centric user-group so I decided to create one.
The user-group is a relatively standard group which focuses on curating KDE desktop screen shots, icons, themes, and wallpapers.
