Suggestion
Participating in certain group activities may require a user to make a post on the group wall, however it is often hard for group administrators to keep track of these messages.

While not the biggest or most important suggestion, I believe this will be beneficial to group administrators, making their jobs a lot easier.
Please reply with your feedback on this topic, it will be nice to hear what you guys think.
I would just like to mention that this idea was proposed by byc14. All credit should go to him.
