I haven't had that particular problem, Carl. My experience is that some Forum members I can email OR PM, and others I cannot.
One of the site issues is knowing whether a message has gone through or not. When you don't hear anything back after sending a message, you don't know whether it even was received.
Thankful for those, like yourself, that I've been able to get through to when seeking parts.
