Anyone who is not a member of the forum is not allowed access to the blogs, Admin & moderators can see all blogs.
If you go to blogs, post to your blog, then on the left side click on blog options, at the bottom under permissions and privacy there are options to allow or not: members on your contact list (disabled function), members on your ignore list, everyone else. You can also allow or not members to post comments.
I'm assuming (and you know what that means
) that if you
uncheck 'contact list', 'ignore list' and 'everyone else' that the blog is completely private except for admin & mods. Of course you could pm Marko to ask, or try it posting something
not important, a "test" if you will, uncheck all the boxes & I'll tell you if I can see it
