[Plugin: cformsII] remove cforms link at the bottom of every form

I think that editing my theme’s stylesheet will not help because the theme has really nothing to do with the plugin cformsII. There should be a file among various cformsII plugin files where I’ll have to do some editing to remove the link – cforms contact form by delicious:days. I’m looking for that file. If anybody can tell which file is that, please help.
