Welcome to the Citizendium! We hope you will contribute boldly and well. Here are pointers for a quick start. You'll probably want to know how to get started as an author. Just look at Getting Started for other helpful "startup" links, our help system and CZ:Home for the top menu of community pages. Be sure to stay abreast of events via Twitter. You can test out editing in the sandbox if you'd like. If you need help to get going, the forum is one option. That's also where we discuss policy and proposals. You can ask any administrator for help, too. Just put a note on their "talk" page. Again, welcome and have fun!

You can find some more information about our collaboration groups if you follow this link CZ:Workgroups.You can always ask me on my talk page or others about how to proceed or any other question you might have.

Earth science

Thanks for the input on the article. You wrote: "By reconstructing the positional drift of masses of bedrock, geologists have been able to determine that the the Earth's magnetic field has reversed polarity several times in the last 3 billion years." Do you have a source or two? I will look for online sources but a text or journal article would be nice. - Thomas Simmons 15:13, 20 April, 2007 (EPT) --> sent him several references.
