Sometime ago I have written a post about removing Blogger Navbar. Many bloggers like to remove it. But it is not legal for all blogspot blogs.  You are permitted to remove it only if you self-host your Blogger blog i.e. publish it via FTP. And I doubt if anyone of you do that. It’s certainly not a great idea when you have WordPress to use. Here is what Blogger support has to say about the removal:

Unless you publish your blog via FTP, the Navbar cannot be disabled.

So before you do it, remember it.
