Chill Download has compiled quite an impressive list of 20 great WordPress plugins, ranging from SEO to e-commerce integration, social media enhancements, a shortcode utility (at last), two events-related plugins and photo gallery generator as well as several slider plugins.
On of my favorite is WP Auctions and I guess I’ll be implementing it in the near future in some project.
WP Auctions is a plugin that lets anyone with a WordPress powered blog or site host their own auctions.
You can use it to sell anyting you like to your readers in an auction format.
