Hello Swang, and welcome to Wikipedia! The first thing you should know is that we encourage you to be bold. Feel free to edit and improve articles, by clicking any 'edit' link.
If you'd like to test what Wikipedia can do, check out the sandbox - just type and save the page and your text will appear. That's the beauty of a Wiki.
For more information check out our tutorial - it's designed with newcomers in mind, as is the help section. If you'd like to get involved with current projects, have a look at the Community Portal. There are always tasks for users to do, ranging from copyediting to expanding stubs.
I hope you'll enjoy your time here, but be warned, it can become addictive! Feel free to message me, I'm more than happy to help. As an added tip, sign any message you post so users know that you've said it. To do so is delightfully simple, just use the wikicode ~~~~.
Once again, welcome!

Please stop blanking pages or adding nonsense to Wikipedia. It is considered vandalism. If you would like to experiment, use the sandbox. Thank you. Academic Challenger 23:57, 18 February 2006 (UTC)
Please stop. If you continue to vandalize pages, you will be blocked from editing Wikipedia. --Jiang 16:00, 19 February 2006 (UTC)
