neobux: How do I recycle referrals?

To recycle a single referral, the easiest method is to click the green icon (the two arrows) at the end of the referral's row in the referral listing.
Click it and then just confirm that you really want to.
Using this method, you can pay with your rental balance or get the amount deducted from your main balance if your rental balance hasn't enough funds.

To recycle a group of referrals, just tick every checkbox at the end of each referral's row.
Then, scroll to the end of the listing and you'll see an option asking you what you want to do with the referrals you selected.
You may want to do many things to or with them but we only give you the options listed there.
Just select that you want to recycle them and confirm.
This method only works with your rental balance.
