Extra Information:It works by recording each account you login then making that account available for use by manipulating the login info in the domain's cookie file. As long as the expiration time (selected on the login page) is still in-effect the login info is still considered valid by the server.

Login on one account you want available then logoff and login on another you would like to also use. Do this as many times for as many accounts as you wish to have available then when you are ready to make a post simply select the account you would like to use for that post all from whichever account you're currently logged in on. You must select which account you want to use before typing anything since the dropdown disables itself once typing starts in order to avoid losing what was typed. You can set the expiration time for the logins to "forever" to always have those accounts available and never have to login on those accounts again. However if forever not chosen and an account expires then the code will notify you which account(s) are no longer valid.
