Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
Does anyone know who runs the above site? Whilst it is a superb resource, there are no "Contact" details shown on any of the webpages and it appears to have developed some technical hiccups over time that make it less useful than before.
Andy Powell, used to post as cavemapper on this site, don't know whether he still does. (He got the Arthur Butcher Award in 2010 for the cavemaps site).
