PACKT Publishing, publishers of several books on open source software, is looking for people to submit the names of Open Source Content Management Systems in several categories. It's your chance to show your support for your favorite CMS, and doesn't cost anything more than a few seconds of your time.

The CMS's that receive the most nominations in each category will then go through to a final stage, with winners voted for by a panel of judges and visits to www.PacktPub.com, based on a number of factors:

• Performance
• Usability
• Accessibility
• Ease of configuration and customization
• Scalability
• Security
• Community contribution
• Support (suggested additional factor)
• Available add-ons (suggested additional factor)

Nominations for each category will be open until Friday, August 31. You can nominate RavenNuke for Best Open Source CMS and Best Open Source PHP here.
