I'm webmaster for http://ncwildflower.org and http://ruralintelligence.com programming in ExpressionEngine - with both since 2007. I love ExpressionEngine for big, database-driven sites. The search power of EE is really fantastic! (Version 3.x.x even more so!)
I also maintain several of my own sites, which are mere blogs, so I use Wordpress for those, and the infinitely customizable HeadwayThemes.com themes for all 4.
I am an electronic musician and enthusiast since 1972. I use Samplitude Pro X2 Suite, Harrison Mixbus 3, and Cakewalk Sonar Platinum.
