weblogs.com update?

I couldn’t find more information about this, but it seems that every time I update my blog, something is “phoned back” to weblogs.com and my blog gets listed on that website (I am too scared to post anything and test this, fearning that my blog may become public). Basically, I want only my closest friends to know the URL of my blog.
I don’t want this to happen! What should I do?
I made sure that I did not follow the “The weblogs.com cache file needs to be writable by the web server. CHMOD 666 the weblogs.com.changes.cache file.” step in the installation and I am wondering if I need to do anything else.
Thanks,
Chris
