I was browsing today, and have seen this offer of 2 free .com and .net domain. I have already been register to it, and I think its very easy to get. Go for it and subscribe to their website.
Here, I have got the link below,
Free Dot com & Dot net Premium Domain Offer
UPDATE:
I think you have to complete an offer also to get fully subscribed through this free domain offer. But, leave it if you are lazy [ like me] then don’t bother -:)
