[#53420683] Updates the create your group page. 


Also:

Merged the content of post-1-configure-settings-features.html into post-1-create-a-group.html because post-1-configure-settings-features.html was really just the second half of post-1-create-a-group.html. 

Removed post-1-create-a-group.html because it was confusing to have "create-a-group" and "create-your-group" and "create-a-group" is very nearly identical to the index page for this section and is not a tutorial.
