An Odoo site has one to many blogs. Is there a way to have only one blog and have it be the default, or at least delete blogs that I accidentally created in the past so there is only one blog? 

Right now my blogs menu looks like this: https://cln.sh/AyCf9T

Ideally, I wouldn't have this menu and just have a single blog. If that's not possible, at least I need to be able to delete/rename the list of blogs but I can't find a way to do that.
