Over on ~creative, the idea of a regular photo challenge came up, which I think is a great idea and I'm looking forward to having a go at. But I'm notoriously bad at remembering to keep track of stuff like that.

What might be useful to help solve that problem would be the ability to subscribe with notifications. So I can get a notification - perhaps in 'unread', perhaps in a separate area - when a post is made with the tag creative.photochallenge.annouce or in the group ~creative.photochallenge, meaning I don't forget about that week's challenge announcement.

This could be useful for other things you want to keep track of: music.newreleases or hobbies.geocaching or whatever particular thing you're slightly more interested in than just being subscribed to it.

While I also appreciate the ability to read things without marking them as read, it took me a minute to figure out how to mark things as read and now I find it more of a burden than anything. Would it be possible to implement functionality to mark things as read if you click on the message in your inbox?

Sometimes I even reply out of my inbox and it keeps it unread. While I sometimes keep emails I've replied to as unread at work, I can't see any reason I'd want to do that on a social media website. Maybe that's another functionality that could be implemented?

I'm curious to what extent group mods will be able to customize how groups work. One thing I think is very limited about Reddit is its very limited, constrained format. Some communities might be better served with different options. Is there a doc explaining what is planned?
