@fffan2008: Given the gradual rerelease of existing content to the new site, including the fact that the MSPAs prior to Homestuck are not yet available beyond their first pages, and the newspost that links to HSBC, we can guarantee you that the rerelease of the Epilogues on the new site are coming. In the meantime, you can read the Epilogues through Wayback archives of the Viz-era website[1], the Unofficial Homestuck Collection which is still as available as it's ever been[2][3], the kici.moe mirror[4], or hell even as an ebook[5].
