I moved my newfunny.com and boulderkinetics.com websites to a new home and I didn't add any email accounts. My current email address in olutfey@gmail.com.
I saw some wordpress plugins that manage email lists, but with my level of organization I would collect all the names and then lose the password :) Besides, what you have set up on the kineticists site is what we could use, but with only one person who can post messages. Does that make sense?
