how do I request for paying from mylot ?

Mylot pays you automatically if you have made at least $10. You don't get the money at the end of the month but later on. You need to make sure that you have set payout to $10 though as if it is set higher you will need to wait until your earnings reach that. If you are using paypal you need to go to paypal and confirm the amount or else it won't go into your paypal account.

You don't have to request payment from myLot. Just participate as you have been doing, and when you hit $10 or more, wait till the 15th of the month following the date you hit $10, and myLot will automatically deposit the money into your PayPal account, if you have one, or another account... can't remember what other account, because I'm with PayPal, but they accept a couple of other providers as well, but not many.
