Apparently the tweak I put in caused all the poster information on the left of each post to be hidden in IE.
May take me a few to track down exactly how to get IE to behave. In the mean time, there are 4 other free browsers out there that work perfectly (Firefox, Safari, Google Chrome, and Opera)
Also, switching back to the old look should correct the issue also. You can do so at anytime using the drop-down list on the lower left of any page in the forums. Select "IP.Board" for the old one, "Light" for the new one.
