#22 Google does not consider the dots (.)

If we use dots in the mail address it will not consider. 

Its quite surprising and interesting. We have been using gmail since years.But you may not notice this feature.
It doesn't "recognize dots (.) in username". At gmail Log in page you can enter any number of dots in username. gmail ignores it as such.

 For example if your usenrname is xyz@gmail.com then,if you enter
 x.y.z@gmail.com
 x.....y.z@gmail.com
 xyz...@gmail.com
 or any number of dots , with same password it'll log in successfully.

 Try it.
