We'll be meeting a week early this month, since our regular date would be on Thanksgiving Day.
Advanced WordPress Meetup
Discussion in Theme Design, Plugin Development, advanced Security, and other more advanced elements to WP.
You'll probably want at least a basic understanding of HTML, CSS, and PHP to get the most out of the Advanced Meetups. Feel free to give it a try if you're on the fence and you can also attend the User/Beginner meetup to see where you feel more comfortable.
