Thread:Project:Support desk/How do I change the Tab text and the URL of my landing page?

I just installed MediaWiki on my laptop and got it running fine. I'm stuck with how to change the Tab text of the tabs that appear at the top of the page, left of Read | Edit | View History. Right now, the tabs read Page | Discussion, but I'd like to change it to Bikes | Discussion. How can I do that? I've gone mad trying to figure out how to do this. I've found all sorts of information on editing certain pages with `MediaWiki:***` to do this, but where are those pages located and how to I reach them?

Also, I've noticed that many Wiki sites have a URL like http://en.wikibooks.org/wiki/Main_Page -> Note the word wiki in the URL. Mine reads http://localhost/bikes/Main_Page. How can I change the word `bikes` to `wiki`. I've Installed MediaWiki into a folder called bikes.

I'm doing all this on a Laptop running Windows 7 64Bit and using Apache and PHP

Can you please help me?
