It has no effect on the kind of content that can be hosted on a site running the MediaWiki software. Wikipedia itself licences its content under the GFDL, so that the encyclopedia articles themselves are licenced to be used in various ways by anyone who so wishes - obviously a law that fell under a more restrictive copyright would not be compatible with that. But there is no compulsion to use the same licencing arrangement just because you use the same software - if you set up your own wiki installation, you are as free to choose its copyright status as you would be for any other website. Similarly, you are free to modify the software in any way you so wish, such as to accomodate banners or interface changes. Here, the GPL does have an effect - IANAL, but this is my understanding: if your site is publically accessible, the exact nature of your changes to the core software must also be made public, since the GPL forbids you to have users who cannot build further on your changes. Basically, if you improve on the work given freely by others, you have to give your improvements equally freely. Hope this clarifies things a little. -- Rowan Collins BSc [IMSoP]
