First of all before you request a payment you need to be sure that you have enough points $5 minimum to LR and AP and $10 to Paypal $5 is equivalent to 500 points and $10 is equivalent to 1000 mtv points. When requesting you have to follow the format here is an example:

blappy - 2nd payment request [LR]

Username : blappy

Amount : 500 points.

Payment processor : LR

ID : U7984006

Thank you Admin and Moderators.

That is an example your title must be somehting like this
blappy - 2nd payment request [LR]
and the content as you can see it contains username, amount, payment processor, Id, and your message if any.
