I get quite a few messages through the email contact form- usually at least a dozen per week that ask questions about WCF. For the past year, I've been able to reply to nearly all of these with a wait of no more than about 1-2 weeks. By the way, if you have a question that you'd like to get answered sooner, then you can frequently have responses within hours when posting to the WCF forums. When you use the contact form though, you need to give a valid email address if you'd like me to respond. If you leave it blank or put the wrong address in, I have no way to contact you. Many questions eventually get posted as articles but that generally happens months after I've received the question.
