this is scam? what ur mean?
No this isn't a scam, but the website stands to make plenty of money.
Literally hundreds of domain name extensions are proposed each year. Very very very very very few make it to be real domain extensions.
This site (or company) want to be a sponsor this new .free extention. Have a large sponsor never hurts, and this site also allowed them to prove there is plenty of interest.
If (or when) it ever gets accepted, they will most likely be the authoritative registry of the .free domain and will make millions. (Similar to how Verisign controls .com and a few others)
If you pre register it seem that all that does is help them prove interest and give you first dibs on registering if it become a real extension.
It looks nice.
When compared to Co.Cc or .Tk.
Just to be clear.... There is nothing on their website that makes me think they will be giving these domain away. They will most likely cost money.
