Hi Cybernetec,
Thanks for an excellent hack. This was by far the best hack I've installed out of the 73 I currently have! Keep up the good work!
I do have one slight problem, though. If you look at my test forums,
http://test2.prophecy.co.za, you'll see that there is this weird line break after the first subforum, if I have the settings set to use more than one column. On the settings set to use only one column, all the subforums has line breaks after them, which I think is also wrong, looking at your live demo.
I also attach a screenshot of the line break in 3 column mode, as well as single column mode.
