Hi fenz, I am going to tell you some sites which really offer free domains. I ‘ve already taken two domain names from these forums. We have to post on their forums. Here are some links of forums with details:

1) Idotsource => They offer free domains of the extension you want. Register on their forum and start posting. They give 1 point for a post and 5 points for a new thread. A domain name is available for 200 points only. It will take only a week to reach 200 points. Don’t worry they ‘ll surely give a domain name for free. I have already taken a domain name from them. You should have an account on domainsite.com. Just PM admin when you have enough points(200) with your domainsite account number. He ‘ll transfer the domain name to your account. Its very simple. They also offer 500 mb quality cpanel hosting for 250 points for one year. There are also many fully developed sites to win. So what are you waiting for? Register on Idotsource and start posting now!

2) Namepros => Another forum which alco give domain aname for free. You will need NP$ (NP is their forum currency). I have also taken a free domain name from this forum. Their prices are following:
.com 575 NP$
.net 575 NP$
.org 575 NP$
.info 300 NP$
.biz 575 NP$
But getting 575NP$ is very difficult task. Good luck to get the free domain from Namepros.

3) D4free => I ‘vent tried but it is also good. the give only 1 doamin for free for 200 points. They offer 2ponits for a new thread and 1 point for a post and 20 for refferal. I ‘vent get a free domain from them. Getting active on the forums later is also required. So i recomend you Idotsource.
Thanks.
