Gmail accounts are not getting added

When you forgot your account name from a Gmail, hotmail or Yahoo account you never can login to you account. When you have a mail account from your phone or internet provider, with a POP3 and STMP server and you even don't know the server names, you can't login.
When you have the correct account name and password, just goto the login site from the mail provider in the browser. Fill in account name and password and click login. That should do the trick.
For the POP3 and STMP server mail, you first should setup the server settings for both POP3 and STMP in a mail program like Outlook or Mozilla Thunderbird

Simple really, Logout of your other one, search up gmail, click on first link that isnt a add, under neath login box should be another link saying "Login with different account" click that, then click add account and sign in
