Primary site id 1 domains

How can I setup a proper MU where the primary host domain (ie site1) is useful?

If you are going to have all domain mapped sites then use a subdomain of one of your domains for the main site.

OK I have 3 semi related Q’s.

How do I edit Siteurl for site 1 to a subdomain? It’s greyed out.

How do I set a subdomain WP blog?

In Create a Subdomain I set *.domains.net to /public_html
In NS I added A record *.domains.net to IP

I have a blog setup as domains.net/test

In plugin I added test.domains.net (I’m not sure if need same slug)

It doesn’t work using test.domains.net.
WordPress is installed in the root webfolder

Does this plugin work for single installs? I’d want to be able to set the primary domain to something different to my host’s primary domain.

If you edit the site url of your main site you will take your network dwn – that’s why it’s greyed out.

What do you mean by “It doesn’t work” ?

No, it does not work for single installs.

Sorry, for clarification on the first point – recreate your install from scratch on a subdomain.
