How do I launch my site

I have completely designed my site and I’m ready to launch it for others to see.

Right now, I have a “coming soon” page that people see when they go to http://www.columbusurbanlife.com. How do I get my actual wordpress site to show up now that I am done building and designing it?

Any help is appreciated. I have been all through the forums but unable to find a resolution for my issue.
