E-mail is my preferred method of contact. My current e-mail address is KRGuidry at MistakenGoal.com.
I have a Twitter account and although I don't often post I am often monitoring various hashtags and mentions of my own name. My Twitter username is @KevinRGuidry. I have usernames on several other services (Skype, various IM services, etc.) but rarely use them; please ask if you'd like to contact me using one and I'll give you my username and log in.
