Reffer a friend code.

Hello, I wanted to subscirbe and I received information that I can use referal code from a friend before subscribing.
I've asked my friend and she put in my e-mail more than one hour ago and I still didn't receive the code.

How long do I have to wait for the refer a friend e-mail or is there any other way she can obtain the code that I can just copy and paste?

Thank you very much in advance.

It's immediate. Maybe its in your spam junk mail. Have a look at there to see if you manage to find it.

Your friend can also email the code to herself and then just tell you what it is.
