Hey Andrew,

We are trying to find the correct way or quick way to 'Drafts' for our bloggers in the frontend. Can someone let me know where this is located?

The quickly way you have to create a menu item for revision layout menu type from backend menu manager.
After you created, when the blogger view on this menu, they can select `draft version` and filter it.

Secondly, what is the easiest / best way for a Bloggers menu in the frontend? Is there a module or maybe you can advice another way.

Do you mean show all the blogger listing page? If yes, the quickly way you have to create a menu item for this `(Authors) All Authors` from backend menu manager.

Hope this help.
