There is a serious bug.
If you write the text in TextArea and forget to put the Title, when you click on Save, you get a warning that you cannot save the blog, and it delete all the text you just wrote.
This is very annoying, especially if it has been a long text.
The engine would have to warn you that the Title is missing and then allow the user to save the blog.
As provisional workaround you could put a fixed generic title that the user will then modify. This eliminates the possibility of losing the text, while solving the problem more consistently.
