We were all new to something once; riding a bike, driving a car, writing, reading. What is important is the will and desire to change and improve this text rather than the actual changes themselves. If you see something that you think is wrong, needs improvement or is missing, but are not sure how to change it or don't want to change it yourself, please leave a note on our discussion page - just click on the "Discussion" tab at the top of the page, click an "edit" link and enter your thoughts.
