Was wondering if it is a problem to have WWW in the url of the mainsite. It seems to work, but I want to be sure I'm not missing anything before adding more sites to it.
I setup my subdomain wordpress multisite install with: define('DOMAIN_CURRENT_SITE', 'www.mymuwebsite.com');
I noticed that subsites get URL's like subsitename.www.mymuwebsite.com
As I use the MU domainmapping tool it doesn't seem like a problem, or I'm I missing something?
