ok let's try to go step by step :
- log in with user and pass you should obtain something like fig 1

- to post click on "new post" and you'll get something like fig 2

- while reading the blog you can post simply by clicking "new post " upper right corner of the screen
- then add a title, a body text and if you want some images by clicking browse button or typing its url


- then if you are satisfied publish the post so its visible to the other authors

- From now on every author can add a comment by clicking on comment (this one does not include images, images are attachable only by posting not commenting )
