Google - I have a gmail account, can I add a second. I don't want to replace the original email?

Hey boston77!
You can add another gmail account by clicking "sign in".
You should be able to find this button in the top right corner of the google homepage.
You'll most likely be asked to sign into your original account, however, you'll press the "sign in with different account" option.
This will lead you to signing in with a different email.
Under the box for signing in, there should be an option saying "create account".

Hopefully this helps, and this definitely isn't the only way to create another account (just the way I do it).
