Thinking of changing your current wp theme or just plain bored? I have here few preferred links offering Free Wordpress Themes ready for download.
*support the "post thumbnails", a new feature initiated in WordPress version 2.9
*has large collection of premium Wordpress Themes that will surely satisfy your eyes and of course, the readers of your site.
*These themes are 100% free for personal and commercial use given you follow the creative commmon license. Or simply stating that Theme Author Credit links in the Footer MUST remain intact.
*Site is very easy to navigate.
Enjoy!
