For those of you who long for the good old days, they're back, sort of, if you want them.
I have installed a style called SubSilver2 that is pretty close to the appearance of the forums before the software upgrade. If you want the board to look more like it used to, go to your user control panel, click on the tab for Board Preferences, and in the pulldown menu next to "My Board Style" select "SubSilver2." Click on "submit," and go on with your old school self.
It's not exactly the same, and all the new features of the software are implemented.
Next step: installing American English so we don't have to read about "colours."
