George Beccaloni and I have been working on a new website for the Blattodea Culture Group (BCG). The new website is hosted at the Natural History Museum and has been developed using the EDIT Scratchpad system (essentially a development of the Drupal CMS).
The website is now online, and has an ever increasing amount of information. If you join the BCG you will have access to even more information, including a large number of PDFs of old papers, contact details of a panel of experts and access to a large number of species reared by the Livestock Co-ordinator.
The new website also has a forum where you can discuss any topic related to cockroaches or even exchange livestock (as long as you follow the rules).
