While the incorporation of PMs into the group wall has made the feature immensely more useful, it's a new feature that needs a little bit of tweaking. Having notifications for the chat is nice, but having constant notifications that are indistinguishable from PMs can be a little annoying. I feel that Hylebos' suggestion of having a separate notification system for group walls could be an effective way of managing an excellent new feature, as it will keep message notifications reserved for private messages while still notifying the user of group activity.
