@Blonde Jon wordpress? - maybe no, it's good but i need other cms because many mt site using it. @ascetic drupal? i will try. http://www.itechstyle.com/ is using DRUPAL?
I'm using Joomla on my site for tutorials. I like it for the option for putting a forum on the site later.... so I'm not the only one answering questions to peoples quiries about my tutorials... plus the flexibility of adding other extensions in the future... Lhlalyam
You might try Moodle - it's specifically designed for teacher/student interaction. Bit of a learning curve, but it might save time over trying to get Joomla or Wordpress to do what you want.
with drupal you can almost create every website. But the learning curve may be steep. I prefer drupal.
