Editing comments has been implemented and we'll also call this one a beta phase. So let me know if you run into any issues. Reporting comments will be the next thing I add and that should also be released tomorrow sometime.
After all that is set and done I will actually work on the two features I've been meaning to. The review page, to read all reviews not just the latest 6. The other being the applications system. That's a bit more complex and will take more time.
