The best way to get in touch is to reach out via a tweet on Twitter. I check my notifications regularly and will definitely see your message. My username is @benlarcombe.
I am not the best at managing my emails and have been known, on occasion, to reply to unread messages months after receiving them. However, if you would still like to email me, please use ben[at]experttabletennis[dot]com. It may not be possible for me to reply but I do enjoy hearing from you.
