On the CodeWalrus forums, whenever I click on the blue "ti-83+/84+" flair (flairs - is that what they are called?), I am taken to a new tab entitled "Set Search Parameters." There, I am told that there was a search for "[ti-83 /84 ]", which evidently does not follow the rule that Each word must be at least two characters long. When I click on the other flairs, I am able to see actual search results that correspond to the flair. 

After further testing, the only time anything ever happened at all when I clicked on a flair was on 1 browser (Google Chrome on Windows 7 64-bit.) On other browsers (Firefox & Google Chrome on Windows 7 32-bit), nothing happens.
