Before you hit send.
Do you offer consulting or site surveys?
A few times a year, for schools, libraries and non-profits. Describe the building and what's going wrong in the form above and I'll tell you straight if I can help or hand you the name of someone who can.
Can I suggest a topic or report a mistake?
Please. Corrections are my favorite kind of mail. Send the page, plus a source or a capture if you've got one.
Can I use your diagrams and tools in my course or slides?
Free for classroom use with attribution. Ask me first for commercial training material. The answer is nearly always yes.
I didn't get a reply. What happened?
I answer inside two days. Nothing after that, check your spam folder, then send it again. Even email needs a retransmission now and then.
