Editable opening times

I've made a new version of Opening Times available at http://beta.opening-times.co.uk. This new version allows users to register and then add and edit the opening times directly. I'm hoping to build a community of editors to help gather and correct the opening times information. Please register and let me know what you think or if you find any bugs. I've also made the project open source under the AGPL, so if you fancy helping out please get in touch.
