I'm looking to set up a website/forum and am looking to encourage user participation with users able to start new threads. The last time I designed a website was when Dreamweaver was in its infancy and I still ended up writing a great deal of HTML by hand . I'll obviously need a database driven site and have chosen MySQL for that purpose. However, I'm unsure of the best Content Management System for ease of use, stability and security. I understand the hallowed Arrse is run using PHP but I've heard that unless you know the ins and outs of PHP then security can be an issue. Alternatives include Plone, Drupal, Ruby on Rails and more. So, can any of you technology wizards give me a push in the right direction? Oh, and I'll be using Apple Mac, but could run Linux instead. I most certainly will not be running Windows. Cheers.
