quote mojomonkee:
"try to find a theme that has one single *.rc file and loads only the core modules and a few others. that way you can play with the settings and stuff and not be worried about totally fucking the theme up. this has just been my experience and it has taught me how LS themes work quite well. "

For actually learning LS, I couldn't agree more. Maybe a decent themer would like to take this task? Some sort of defaultish theme...
