If you have recently tried to e-mail me to the address linked in the sidebar to the right, your mail will have bounced back.
It seems I hadn't bothered to check that particular Yahoo e-mail in over 4 months, and they turned it off.
I've fixed that problem -- by now accepting comments to me - suggestions, alerts about typos, whatever -- at zizonus -at- gmail.com.
Feel free to drop me a line. I promise not to wait four months to check the mail.
