I want to customize WordPress, but I don't want to ruin WordPress default theme 1.6 by Michael Heilemann. What I can is duplicating the theme folder. My new theme name will be "Imized". I copy the whole folder default in wp-content/themes and paste to newly create folder named imized. That is not enough. I won't see "Imized" theme in Available Theme section. What did I miss?
More one step, which is editing the comment inside style.css:
The theme won't be display if the name is the same. After previewing my new theme "Imized" in Available Theme section, I click Activate Imized to activate my duplicate theme.
