I wish I could be a little more forthcoming, but I've found that if I put a link to my email address, I get more spam than real email, so I'll phrase it this way:
G, then an underscore, then M, followed by an "at sign", then mcraefamily.com
That's my email address -- feel free to ask me math questions, tell me your philosophy of life, whatever you like, as long as it's a personal email from you to me. Please, please, don't send me any spam! Thanks!
Or, if you would rather use this form to send me email, that's OK too. Remember, I can't reply to you unless you supply your correct email address.
