I think there is still some good information in them, especially for someone interested in researching the history of frequent flyer programs. In my own case, I wondered how TWA's FFP was structured since they died before I became actively involved in FFPs. As such, the old TWA board served as a useful resource for my research.

Perhaps they could be archieved and moved somewhere else so that the information in them is not lost, while also serving to clean up the main page?
