Yes, I've done a few things over the past week. Server upgrades, tuning, etc.
I am trying to tune the performance of the home page so it loads faster. That's the reason for combining the for sale sections back into the General Discussions for the time being. I also shut down the top posters block since it takes over a second to execute and I'm still working on a faster way to do it. I'll put things back in order shortly.
