Remember that email addresses change often. I do my best to keep up with this, but the Guru is only human. I can't guarantee any of these addresses past my knowledge that they worked for me and for others in the past.
If you find an address that doesn't work, let me know. I'll do what I can to find a working contact. It may take me a few days, but I'll do my best.
I'm always fine-tuning the list and adding addresses, so check back often. If you have an address to add to the list, send me a note at the address below.
