If you have a Gmail account, you’re in luck. Gmail has a cool feature
which
allows you to alter you address just by adding a dot anywhere in
your username.
For example, johnsmith@gmail.com could be
john.smith@gmail.com or
j.ohnsmith@gmail.com. The cool part is that all
your messages will be sent to
you arrive in your mailbox. Why? Because
Google ignores the period. Twitter,
however, doesn’t. To Twitter, this
is a completely different address.
Another way to use on email
account for different Twitter handles would be by
having the typical
@gmail for one account and @googlemail.com for the second.
You could
probably do this with alias and domains as well. Or, just forward
everything to Gmail.
