Link to category in main menu

I have this website: http://wp.bcomsolutions.ca/
What I want is for a “news” link on the main menu to point to the ‘news’ blog category (http://wp.bcomsolutions.ca/archives/category/news). I’m brand new to WordPress and I don’t understand the menu system whatsoever. Right now, the news link just goes to a news page. Instead I want it to link to all blog posts in the news category. Do I need to delve into the template code? I figured something like this should be simple enough through the interface. What am I doing wrong?
