The account in question has it's e-mail address as "dnnmanagers@co.geauga.oh.us". This was an existing account which was copied over when YAF was installed.
I tried changing the e-mail address to me@home.com, and this saved. Changed back to the original and it errored out stating it was invalid and it e-mail address is still me@home.com (which I can change in the db, no problem).
Thank you again..
