Is there any sort of prioritized TODO list, either by difficultly or importance? And that's not so I can knock out some big feature and be the hero, but so I can whittle away at some of the more nagging edge cases and make some random developers day when things just work.
Even just making a little Rails app or script that re-produces the bug would be helpful. Writing a test case that's failing would be mega helpful. Fixing the bug would be incredibly helpful. :)
The issues page is the best you have for that, sort by popularity or something like that.
That's one of the only things I'm frustrated about - I wish there were a clearer list so that I didn't have to troll for tasks that need doing, or ask a core member on IRC/campfire
