I installed a total of about 12 themes. Most of the themes still need tweaking. The members of my forum are asking if the Fluid View can be fixed to have a solid background making the topics easier to read and also the sidebar where you can check which topics to view. It's not just one theme, I would have to fix about 6 of them. I can manually edit the template or CSS, but need help on where to edit in the template.
Members requested a background such as in this theme that seems to have one.
