Hi guys,

I'm new here and sorry if I'm posting this on the wrong section. I'm in the process of starting a website, haven't picked a name yet, but let's say the name is [nathandrakessite.com...] and that will be the main site, I would like to create a mirror site, i.e. a subdomain (i.e. [mirror.nathandrakessite.com)...] so that I can properly test the site in the future and then when everything is working I can implement my changes to the main site. My worry is that:

1) Google or another search engine will crawl that subdomain and people will find it
2) People will randomly find it

Is there a way that I can make it so that it's private and no one can access it?

My second question is, I'll be using PHP and MySQL, now I have coded on PHP and MySQL before, but never had to worry about supporting mobile platforms which is something I want to do with this site. Any helpful tips on that? Do I need to develop a new site altogether (let's call it m.nathandrakessite.com) and redirect users there with a PHP script? If so is there already an existing script in existence? Do I also have to design iphone, android sites, blackberry, etc (iphone.nathandrakessite.com, android.nathandrakessite.com, etc)?

My third question is where to buy the domain name and host? I'm thinking 1and1 is pretty cheap to buy domain names (U$4.99 a year) and hosting on hostgator (<$10/month). Are both of those good and is hostgator compatible with osDate? I know there's a limit on the number of files I can have with hostgator, but if my sites get big, I can just update to a dedicated server.

Thanks
