WordPress is the most popular CMS around. We meet monthly to discuss WordPress related topics. We have recently changed our meet up format. Instead of 4 speakers taking that stage for 30 minutes, we now invite 3 speakers to talk about something WordPress related for 25 minutes. Then we hold an Open WordPress Discussion that lasts for 45 minutes. Anyone can ask a question or answer a question during this Discussion. There are so many smart WordPress users in this group. So we decided to let everyone answer questions. Not just the speakers / organizers. It takes a commited group to build a community.
