A few other useful tips: Please sign your name when you comment on talk pages (not articles) by using four tildes (~~~~), which will show your name and the date. When you edit a page, even minor edits, you should include a descriptive edit summary. If you need help, Drop by the Help Desk or the New Contributors' Help page. Another option is to join the adopt-a-user project. You can also add {{helpme}} to your talk page, followed by your question, or ask me on my talk page and I can try to help, or point you to someone who can. Happy Editing!- ArielGold 14:32, 17 September 2007 (UTC)
