I am new here and I must say that I fell in love with Sandbox! It's simply awesome! 
What I wanted to ask is, if there is a possibility that I may download a 'clean' version of Sandbox. By clean I mean only the basic engine without any addons from players, such as textures, models, games and skyboxes. I want this because I get confused sorting things out (specially in cfg. files and textures). Being a newb I want everything inside the folders to be 'my creation' only. Any help will be greatly appreciated^^Thank you!
P.S. I know I can delete the stuff, but I made a lot of mistakes doing so and I had to re-install Sanbox many times after that so a clean version would be awesome!
