I need to find out which and how many blogs are hosted in a blog operated by our competition. No worries, I don't want to pirate the guys blog, it's all about seo, we both operate on plumbing in spain, and the guy has an incredible success (seo with google, serp), where as we, doing more or less the same thing, aren't going to far.
I assume the person is using wp multisite, just like we are, but am not sure. So, looking at his source code I wasn't able to find out. I would like to know if there is any way to know which and how many blogs are hosted in a specific multisite domain.
