Please set your name first, follow existing conventions for node naming, categories and locales (detailed in House Style), and leave a comment with a summary of changes (or "New entry" if it is a new entry). If you have an artistic flair, how about improving our stylesheet? Email us if you have come up with one. If you have any suggestions to make, you might want to leave Comments.
Before creating a new node, you should probably have a look at Scope of the guide, to decide whether your proposed node is suitable for inclusion.
We have a flickr group which can be a useful way of arranging new photos to be added to the guide.
