You need to create a cohesive feel between the site and forums. They look like 2 completely different sites. And the reason people are telling you that your banner does not fit your forums is because your banner is a fixed width and the forum is not. So it does not look the same on different resolutions. The banner on the front page looks quite amateurish as well.
Oh, OK! I am having my designers make new banners and we are having a Banner Rotactor.
I am going to ask the designer who made that to make sure it is not big anymore. I will be looking for a good style for the Joomla homepage. Thank you, RL!
