The easiest way to get hold of me is to give me a ring on my mobile number. If I dont answer immediately, I'm not ignoring you - I'll be either driving, or using power tools - I'll ring you back when it is safe to do so.
Emails - I usually check my e-mails early in the morning, and then when I get home in the evening. If you send me a mail at 9am in the morning, dont be getting worked up that I havent replied that day - I rarely use a computer during the day, hence cannot check for emails every hour. I will reply that evening.
Landline Phone. Probably the slowest way of getting in touch with me during the day, though if it is non-urgent, you can leave a message on my answerphone, and I'll call you back when I get home.
