Hi, you can get rights on that site by going to Adoption:Requests. You likely wouldnt need a blog post, simply leave a message on that user's wall asking if theyre ok with it. If they dont respond, youre fine to adopt.

As for makimg the wiki private... i dont knownof any such tool... you may want to ask via Special:Forums.
