If you know PHP and MySQL, and have way too much time on your hands, the FreeRealty project could always use your help. It’s a project that I helped to start and develop, and it’s the software that powers the back-end of Sunray’s web site. It’s a fork from the 2.6 version of OpenRealty that is no longer in development and we’re trying to revive the project, fixing bugs, adding features, etc.. . So if you know a thing or two, join us!
