I don't mean any subdomains,directories or anything like batcave.net, geocities.com. I mean domain name registrations such as .com, .co.uk, .org etc but for absolutely free

You can try kickme.to. That's the only free one I can think of

free forums www.forumer.com

Web registration is not free - not anywhere.

godaddy.com is cheap, not free though, I think you will be hard pressed to find that for free.

Domains aren't free sombody has to pay for them. If whatever ever your putting on their is in high demand you could probably pay for it with a paypal account.
