Question problem with space between joomla and k-forum

The solution is specific to the Joomla template that you're using on your website. I discovered a similar problem with a website that I was helping another user with and, unfortunately, we concluded that the easiest way that the problem could be overcome - without spending a huge amount of time - was to unpublish the module from his forum page.

There may be a solution. We would need to see your website in operation to identify what CSS needs to be changed. Alternatively, if you are familiar with Firebug for Firefox (which is all that I would be offering to do for you, anyway), you could start your own investigation, make a few adjustments, and see if these have any effect.
