Comments and Email
I have 310 unanswered emails in my inbox. I nearly always get around to answering my emails eventually, so if you have sent me an email, please be patient! But if you have a question for me, email (or phone) is definitely the way to do it. Submitting a question in the comments on the blog (e.g. "how do I get hold of this book") will not get you an answer, sorry.
