Hello Mark, welcome to Wikipedia.  You might find these links helpful: How to edit a page, How to write a great article, Naming conventions, Manual of Style. You should read our policies at some point too.  If you have any questions, see the help pages, add a question to the Help desk or (if you want a broader audience) the village pump, or ask me on . I hope you enjoy editing here and being a Wikipedian! *You can introduce yourself on the new users page. *You can find lots more information, including open tasks and daily tips, at the Community Portal. *You can sign your name using four tildes, like this: ~~~~.  *Before saving a page, it's a good idea to use the Show preview button to review your edits. Also, consider writing a summary for each edit. *The Tutorial is a great way to learn the basics in a more perspicuous fashion.  Again, welcome!
