The forums are now running on the new flagship version of IPB. With this new release you should see a brand new skin and further improvements to the Tracker system. We may introduce a custom skin in the near future, but our concentration is on the next 1.5 version right now.
We are currently working on merging to the recent DC++ revisions since we have fallen behind a little. Once we're at that stage, you should see some public testing before we release (to avoid any last minute hiccups).
