I found this site that offers free domains... but only www.####.tk I believe you can only register for a .com or others if you pay to upgrade. The only disadvantage with the free domain - if your traffic falls below 25 per 90days, your domain will expire. You can register unlimited amount of domain names with your free account. Here’s the linkhttp://www.dot.tk This might be a great option for people who are using free methods, but plan to upgrade after the cash starts coming in.
Yeah, I know that website. The problem is also that their website is often down.....Sometimes when you try to visit your domain it simply keeps loading, loading and loading... Another problem is frame cloaking....Clickbank doesn't allow that, but I don't know whether they care about that now.
yeh as bl4ck said, can be unreliable. Also not sure if its optional or not, but lots of the .tk sites that I've been to show ads for free .tk sites, kinda not what you want on your website.
