(I am using Chrome on a relatively new PC - I downloaded Chrome a few weeks ago.)
Links from the alphabetical list that won’t work for me:
Amherst, Barnard, Brown, Bates, UCB, UCLA, Caltech, Carleton, Columbia, CMU, UChicago, Colby, Claremont McKenna, Colgate, Cornell, Dartmouth, Davidson, Duke, Emory, Georgetown, Grinnell, Haverford, Hamilton, Harvard, Harvey Mudd, Johns Hopkins, Kenyon, Macalaster, Mt Holyoke, MIT, U Michigan, Middlebury, Notre Dame, UNC, Northwestern, Oberlin, Pomona, UPenn, Princeton, Reed, Rice, Swarthmore, Smith, Stanford, Tulane, Trinity College, US Merchant Marine, USMA, USAFA, US Coast Guard, USNA, Vandy, Vassar, UVA, Whitman, Washington & Lee, WashU, Wellesley, Wesleyan, Williams, Yale
Notice that they are selective colleges, both LACs and perhaps what were among the “Top CC Universities,” if that old list still exists, the clue being the inclusion of Tulane.
So, my suspicion, not knowing anything at all about website construction, is that these broken links from the alphabetical list went to those old groupings (Top CC Universities, LACs, Military Academies) rather than directly to the subforum. But, happily, the subforums still exist, if you delete the “-link-link” from the address bar.
