Hmmm. Sounds like a cool idea. I'm not a big 'app' user (old lady) but I would think something that tracks days, maybe have message alerts for birthdays (something motivational and positive), maybe a daily thought to ponder (kind of like AA's reflections), maybe something that starts a thread based on specific topics, rather than having people simply create their own threads? Might force people into a more positive, solution oriented thought process if they wanted to participate (kind of like the weekender thread). Something that sends out notifications throughout the day that can help keep people on track. I would also include the ability for the user to select what they would like to be notified on. I dunno. Not very good at this kind of stuff. Good luck.
