My hosting provider, in their infinite wisdom, is in the process of switching email servers.
So, if you’ve sent me a message in the past day or so, wait another day or two and resend it. If you are waiting for a response to an email you’ve already sent, please give me a little time, and I’ll post back here when everything is running well again.
Update: Okay, everything seems to be working just fine now! Feel free to send any email you were planning to. Further, if you’re waiting to hear from me, you’ll receive a reply very soon.
