#2 - Read a profile before having a heart attack.
As in, when you see that "Male, Age..... Somewhere, USA" is a match and you have a cousin with those exact specifics, don't let your blood pressure spike to the point of mild panic. Simply click on the profile, see that the person is NOT your cousin, and all will be fine.
Then, close the match just because you're too creeped out by the initial thought to even consider the person.
#3 - Learn to spell.
If you say that your favorite city to visit is Berlin, Germany, but you spell Berlin wrong, I'm not going to take you seriously and will close out the match.
#4 - Give me your first name.
If you are so cool that you can only leave us with the first initial "E" or "T"..... then, you are obviously way too cool for me.
