NOTE - I AM ANGRY. I significant factor in my decision to go with EE was the promise of PAID support (from expressionengine.com/overview):
Support Included
Our support staff are all professionals who use ExpressionEngine for real-world work. When you need help, you always get it from a paid expert (our community members love to help too!).
As far as I can tell, THIS IS A LIE. I see NO evidence of any “paid experts,” no way of contacting any “paid experts,” and certainly no timely responses from any experts at all. Every time I have a problem with EE, I have to post to the forum, and wait somewhere between 24 and 72 hours for someone to respond. THIS IS UNACCEPTABLE. I can’t afford for growth, knowledge, and progress to take this long every time I have a question.
