I was informed that tentatively there will be about 40 people.

i will be giving a talk about "Introduction to Drupal CMS". LimCS has kindly prepared a projector, so I might do a presentation for 10-15min. We used Joomla too, to start talking Joomla Vs Drupal might not be enough. I would say, go for Drupal (higher learning curve though) you'll glad you did!

Hope to see you guyss ...gals ....
