Go to My BHUZ >manage my items > or my account > my items > manage my blogs, Click on your blog and it will open up in an editing window. Just add on to the blog you have started.
THe key to making it work is to go to the my items tab, not the submit items tab. My Items is for editing and deleting stuff that is already up, submit is for new stuff.

But I think it could use some tweaking, for example if you just edit your blog it doesn't appear in the Blog window on the home page as a new blog to look at, so I will put this on the (long) list as something to work on.
