I have many domains with blogs, all using the same theme. The thing is, if I want to make a change, upgrade plugins, etc., I now have to log into each blog separately. I do NOT want subdomain blogs. I have multiple blogs, each on their own primary domain. Can I setup WPMU to control them? How do I do things like: - make a template change that applies to all the sites? - make a template change that I only want to apply to one site (eg: installing Google Analytics for a particular site) Also, are there any SEO impacts to having various domains get their theme from one place, presumbably on a single domain (if that's how it works)? Is there a problem with Hostgator and WPMU?
