Well, this has been by far the most successful and tested strategy for me. I have made a number of mGinger referrals with the help of this so I would like to share it with you also.

Most of you know about ORKUT and its power but the fact is that ORKUT is very helpful in making mGinger referrals. Just enter your friends profile or some community and click on the latest member on his profile. Now copy your mGinger mail and paste it into his scrap with some modification as shown below:

Get Paid to Read SMS / Make Money from Your Mobile Phone

Hi,
mGinger.com pays you to read ads on your cellphone! These ads are only about your interests.
Not only that, you get to decide when you want these ads.

Just notice the first line that I have added to the original mGinger message. This will help you to get your message read by the ORKUTers instead of deleting it. Moreover, in an hour or so you can send this message to hundreds of ORKUT members and out of which you can expect atleast 10 new referrals to your mGinger profile within the next 24 hours. The result from ORKUT is not instantaneous all time and you must wait for atleast 24 hours to see your referral list growing up.
