some kind of simple CMS

I was thinking of perhaps some kind of simple CMS for small businesses to make a website with pages like homepage, map, menu prices, contact etc... but perhaps this is a bit complex just to showcase the framework. Another idea would be a simple forum, but perhaps someone would have a better idea for a simple project.

I've had a course module and then practical training experience working with the Microsoft's ASP.NET MVC with C#. That was ok, but I'm a Linux guy and have coded (badly) with php as a hobby for some years. I would much rather further my knowledge of php and MVC design architecture which I really liked using with ASP.NET. My front end skills are also up to scratch.
