In my perfect world they would be able to maintain their own sites, utilizing common software that could seamlessly hook into this site. So they would appear as sites here but they would run the software elsewhere. That way they could maintain control over their forums, so if there was a technical or social problem they could go on running. The downside would be related to advertising and such, but this could be worked out with cooperative agreements, perhaps based on traffic. I think seamless hyperlinks would be a great improvement. I dont suppose there is anything available now that could do that?
