The thanks for this code goes to Lynne.

/* Begin dual column css code for forumhome only */
.forumhead + .childforum .L2:first-child .forumrow, .forumhead + .L2 .forumrow {
  border-top: 0;
}
.forumrow .table {
  height: 100px;
}
ol.childforum {
  float: left;
  width: 100%;
  margin: 0;
  padding: 0;
}
.childforum li.forumbit_post {
  float: left;
  width: 49.95%;
  margin: 0;
  padding: 0;
  clear:none;
}
#forums .L1 .L2 {
  clear:none;
}
.forumbit_post .forumrow .forumlastpost {
  clear:both;
  width:95%;
}
.forumbit_post .forumlastpost .lastpostby {
  display: block;
  float: left;
}
.forumbit_post .forumlastpost .lastpostdate {
  display: block;
  float: right;
}
.forumbit_post .forumlastpost .lastposttitle {
  display: block;
  float: left;
}
.forumbit_post .foruminfo {
  clear:right;
  float:left;
  min-width:50%;
  width:70%;
}
.forumbit_post .forumstats, .forumbit_post .forumstats_2 {
  width:20%;
}
/* End dual column css code */

Edit: Add this to get rid of the LAST POST in the category bars.

.forumlastpost { display: none !important; } /* Works with dual column to turn off Last Post display */

Put that in your additional.css and then click save and reload. You get this format>
