You will need to use web mail for email. You can use Outlook Express, Eudora, etc. but you must know about 'Pop Before You Drop' email. This means that you must check your peoplestar.net email BEFORE you can send email using their mail servers. You must use their outgoing mail server.
In other words, if you use these email applications, just check your peoplestar.net email address first and then everything else is normal.
If you don't use these email applications and only use web based email, then you do not need to know any of this. Everything works the same.
