Hi all,

Can you please someone tell me how I can install this on my machine? I don't quite get the meaning of -
Remember to CHMOD "saves" to 777 under *nix servers.

Thank you!

I own a website. I recently built. Its a domain name generator that generates domains name for business startups.

It works fine but it is not 100% accurate. I mean that there are some domains that are taken but this tool shows these as available. Such as separated.com is a domain that is actually not available but if you check it with this tool then it will display as available. Check here: Namobot.com

What can I do to make it work 100% accurate? Any suggestions will be appropriated.

Thanks.
