On what OS are you use the Cream version of Vim? Usuaully, you just save a file named .vimrc to your home directory. Not sure how that translates to Windows if that is your circumstance. I have to imagine there is documentation at http://vim.org to guide Windows users to creating and editing their vimrc file to make the same tweaks and customizations as on other systems. Cream may already set up a vimrc file, you may be able to find info on their project set on appending your own configuration onto theirs, too.
