Routing with regular expression - help please

[eluser]umagrama[/eluser]
Yeah... I thought about having a "/content/..." to distinguish between existing content and everything else. But since this little project will only have 3-4 controllers I will define their routing explicitly in routes.php.

This is a small project, first one in fact using CI, I'm creating a URL shortener for shits and giggles with user registration, links control, maybe some charts. Before CI I'd use htaccess for the redirection. It's so much easier and faster with CI once you get the hang of it.

Thanks for helping me out and clearing stuff up. I love it.
