The Chat Menu at the top: when clicked, a side-box pops up and the user can then chat with the other members. The things I disliked about this were:
- It does not allow to open the user's profile by clicking on their name in the chat box.
- There's no chat history available once you close the window and the user goes offline.
- No Online/Offline status of the user.
- Slow response.
It would be great if you could address these problems.
