These three amazing WordPress tweaks prove just how flexible and powerful this content management system is becoming. Anyone who still says it’s just a blogging tool really doesn’t get it. And yes this is absolutely one more example of the power of an enthusiastic open source community. Viva!

• WP Contact Manager. Astonishing theme package which turns WP into a pretty cool contact management tool, complete with search and notes.
• TDO Forum. WordPress as a forum. Ugly as sin, but fully functional and a great example of what you can do with WordPress themes if you really try.
• Prologue. WordPress as a Twitter clone. Official theme from Matt and the crew. Install it and use RSS to give you a full stream of thought connection to your buddies and/or work colleagues.
