 ::Some editors are not appreciative of advice, so I usually ask first whether they even want to know.  With respect to referencing, I suggest you make use of the cite tool that appears when the edit window is open. On the right hand side of the toolbar, it says 'Cite'. Click on it. You'll then have a second toolbar underneath, with 'Template' on the left. When you want to add a reference, have the cursor in the right place, click on 'Template' and choose the most appropriate option. From then on, it's a case of filling out a form. The field 'Ref name' at the bottom of that form is important; if you want to use the same reference again, it is provided to you via 'Named references' with the name you gave it there. Generally, if you write a new paragraph, you'd also give it a reference, and this is the easiest way to repeat it. 

 ::Other than that, I recommend that you read up on close paraphrasing, as some of the Orange article was too close to the DNZB source.  If you have any queries or would like to have things explained in more depth, please say so.  "
