Filling some deadspace in the SHOWTHREAD template

[scottkoz20]

I am looking at potentially filling some dead space at the bottom of the SHOWTHREADS template. Currently, I have a sidebar forced on for most of my users (removable for my staff and donors) and on some of the thread pages (especially those with 1 or 2 posts), there is some deadspace.

I am wondering if there is an easy way to create 2 or 3 columns that I can add information that could also be on the sidebar (like last 5-10 posts on the site) or something else that can be added in using the same type of structure as the Forum Blocks.

If there is a mod that exists to facilitate with this, awesome... if not, how hard would it be to create blocks like this for content? It could be for paid content potentially as well...

Thanks,
Scott
