Hard to believe, but I've been working on this Rails app for over 7 years now! It started as a Rails 1.0 app waaayyy back when, and I've managed to bring it along through almost every major Rails version (still working on updating to Rails 4.1), which I'm pretty proud of.
You can see screenshots at http://church.io.
Being specifically church software, it might not find much of an audience here on HN, but still, I'm proud, so wanted to post about it.
Keep inspiring HN!!!
