As I do keep repeating, most information about Punch is to be found on this website by looking. I do suggest everybody does study the website, you'll never know what gems you will find. If you had done that you would have found Chris van der Craats' splendid carving instructions and templates for Punch, Judy, Clown, Policeman, Jack Ketch and Crocodile, a wonderful help to beginners. You would also have discovered all sorts of useful information.
All you do is go to the main menu and click "Practical Punch" and then "Punchman's Tips"
Or you could just click
http://www.punchandjudy.com/tips.htmAs for changing your Username? No, I'm afraid not, that is the one thing (in all web programs I imagine) that you can't change. You can change your password but not username. What you can do, of course, is to rejoin as another person. The only disadvantage to that is that your previous postings will still be attributed to Cood123 and not to your new name. What I would suggest you might like to do is leave your username as Cood123 but put your real name in your Signature.
