Sorry, the name is actually Carl Koch.
Thank you Holly,I finally figured out that the e-mail was a private message. I found it today on the site.
What threw me off is that an e-mail alerting you to a private message does not show up as coming from MyCorgi ( as the other notifications of posts being followed do). Instead it shows up under the name of the sender of the message and, if you do not readily recognize that name, it looks like junk...... or suspicious. It would be preferable IMO if MyCorgi simply alerted me that I have a private message.
