Our LouderVoice Business site runs on WordPress. What started as a simple (albeit award-winning!) information site has now become a full blown CMS with access controls and tons of customisation. If you are thinking of doing similar, here is a list of the main plugins we are currently using:

• Akismet – Anti-spam     
• Contact Form 7 – Simple Contact Forms
• Contact Form 7 widget – Contact Forms in your sidebar   
• Custom Permalinks – Create your own URLs   
• Deactivate Visual Editor – Deactivate the visual editor on specific pages/posts    
• Disable wptexturize – Disable WordPress screwing with your content    
• FAQ-Tastic – Build FAQs    
• FeedBurner FeedSmith – For RSS   
• Google XML Sitemaps – Does what it says on the tin   
• Live Comment Preview – Ditto   
• My Page Order – Arange your page menus in the order you want them   
• Search Everything – Search more than page/post content   
• Subscribe To Comments – Keeps readers updated   
• User Access Manager – Access Control to files/pages    
• WordPress Automatic Upgrade – Beats the built-in WP one hands-down    
• WordPress Database Backup – Set it on a cron job   
• WordPress Exploit Scanner – Great tool by @donncha   
• WP-Cycle – Image Gallery for sidebar    
• WP Security Scan – Does what it says on the tin   
• WP Super Cache – Speed up your site by 4 bajillion times. Again by @donncha
