Hello Popadopolis, welcome to Wikipedia!
Here are some tips:
If you feel a change is needed, feel free to make it yourself! Wikipedia is a wiki, so anyone (yourself included) can edit any article by following the Edit this page link. Wikipedia convention is to be bold and not be afraid of making mistakes. If you're not sure how editing works, have a look at How to edit a page, or try out the Sandbox to test your editing skills.
If, for some reason, you are unable to fix a problem yourself, feel free to ask someone else to do it. Wikipedia has a vibrant community of contributors who have a wide range of skills and specialties, and many of them would be glad to help. As well as the wiki community pages there are IRC Channels, where you are more than welcome to ask for assistance.
If you have any questions, feel free to ask me on my talk page. Thanks and happy editing, Alphax τεχ 04:27, 10 September 2005 (UTC)
Hi and thanks for alerting me about this one; it looks like he's stopped for now and all his vandalism is reverted. By the way, thank you for your help reverting vandalism; sometimes between approximately 1600-2000 UTC we tend to get overrun with kids making silly edits and there aren't always a lot of people on RC patrol then.
