And it creates a lot of misguessed addresses.

Would I be: Michael_Rene_Harrison at .. or michael_renee_harrison at ..
or michelle_renea_harrison at .. or..

I like being "meuon" and was the only one for a long long time,
but the practice of using an e-mail address for a login is a bad one.
E-Mail addresses change too often for a lot of people.
