Well, I decided to release the topics hack that I am using on my site, yakster.net. This is a simple hack of the PHP-Nuke 6.5 topics module. I found the original Topics module to be very bland looking, so I hacked the module to make it more visually appealing. I know for sure that it works on 6.5 and 6.7 (it might work on other versions)
