Sukanya,
1. I will confirm with the Webmasters about the multilevel referral commission mentioned in the ongoing awards & rewards list. Not really sure myself whether or not it is a current or program or has been closed down, though we do get some cash credits when a member referred through us goes to the next level of membership as per the program of 'Refer your friends and earn revenue'.
2. Regarding the Techulator Giveaways, you have to watch out for announcements in the forum made by the Webmasters. They may enter into a collaboration with third parties which will offer special products and/or services for free exclusively for members of Techulator. These generally include some kind of software. We have also had a giveaway of an inverter once for the winner of an article contest. However, giveaways are not really frequent since unless the collaboration occurs with a third party, it would not be happening for us!
Regards,
Vandana
