  1. WordPress Automatic Upgrade: allows you to automatically upgrade your WordPress installation to the latest one provided by wordpress.org using the 5 steps provided in the WordPress upgrade instructions.
  2. All In One SEO Pack: out-of-the-box SEO for your WordPress blog.
  3. Feedburner Feedsmith: detects all ways to access your original WordPress feeds and redirects them to your FeedBurner feed so you can track every possible subscriber.
  4. Google XML Sitemaps: generate a sitemaps.org compatible sitemap of your WordPress blog which is supported by Ask.com, Google, MSN Search and YAHOO.
  5. Nofollow Case by Case: allows you to selectively apply rel=?nofollow? to your links.
  6. Zemanta: contextually relevant suggestions of links, pictures, related content and tags will make your blogging fun again.
  7. CommentLuv: show a link to the last post from the commenters blog in their comment. Just activate and it?s ready. Will parse a feed from most sites that have a feed location specified in its head html.
  8. PhotoDropper: lets you add Creative commons licensed photos to your posts from Flickr.
  9. Contact Form 7: simple but flexible contact form complete with CAPTCHA.
  10. Ad Rotate: a simple way of showing random banners on your site with a user friendly panel to manage them.
