I am working on creating a mobile version of the community color web sites.
Ideally, the mobile version of a site should be in a different subdomain. My original contract with my webhost did not allow sufficient subdomains; so, I was developing the mobi in the same domain as the rest of the site.
I checked my site. It now is allowing more subdomains; So, I am moving the mobile sites. Google put its mobile version on a site with the URL m.google.com.
A single M to denote mobile is good enough for me; so, I created an m version of each of the sites, eg m.ProvoUtah.US.
