Maybe it's among those things already being worked on, but I miss having the users location next to the post. I think it's interesting to see where people in a discussion comes from. And yes, I know it's in the profile, but it's alot of work to open everyone's profile.
Even a small flag would suffice.
Also, the "Users Logged In Today" thingy at the bottom doesn't work(or wont show for regular members).
