Hi guys,
the drop by field was made so you could write down the PS.com URL together with your referrer. This would look like this in my example:
http://www.pokerstrategy.com/#referrer=Truthans
or this:
http://www.pokerstrategy.com/#uAHZQ7
In the referrer field you drop your PS.com username.
Reason is that you give the potential new user two possiblities. If he forgets to use the referrer URL than he can still mention your username in the referrer field at the registration. If the potential new user however forgets to mention your PS.com username at the registration but has used the referrer URL from the drop by field, he would also be tracked to you correctly.
It's just a way of making sure that we don't miss out on anybody that you referred.
