Your own email can be used as your username.

I recommend that you use your smartphone to get a Google Plus Account.
Scan this QR Code with a barcode scanner app from your smartphone.
You should see a form to fill out.
Notice username field has a link to click so that you can use your own email as your username. So you need a STRONG password.
Here is a screen shot from my Android phone.
You will get an email to your email address that you enter to confirm that you own it.
Continue to fill the form, click Next Step at the bottom.
Continue to follow directions and you will get your account.
Remember that it will not be fully usable until you confirm your email address by clicking a link in the email that Google sends you.
Once you get your account, you will be able to Write Reviews for places you visit, Restaurants where you dine, Doctors and Dentists and other companies and organizations that you do business with.
Google actually WANTS you to be active with your account.
Use Google Maps app on Android or Google Plus Local on iPhone to search for the business that you want to review. Look for the Write a review button on Maps or Rate and Review this place on iPhone.
You will be glad that you got this setup.
Go ahead, grab your phone and do it now.
The process is quick and it is easier that it has been.
