Go to the board index. Find "The Shipbuilders Build Logs" and click on one of the three types appropriate for your model. Click on "New Topic". Give it a name and enter text and any pictures you want to attach. To attach pictures you browse to a file where you have stored a picture and select that item. Then click "Add the File". Each picture has to be added individually, but several can be added before choosing to finally submit your article. When you are satisfied, click "Submit". As you add new items to show your progress and are keeping track of your time or want to modify the title for other reasons, you can change it prior to submission and it will take effect at that location and be carried forth until altered again. To see how this works, you can check out my article on the Mantua Le Soleil Royal.
