To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here.
I reverted one of your edits, which was to another user's user page. Please edit only your own user page, no-one else's. Thanks.
All the best,
