Life moves on and we have changed the site around, adding stuff, taking stuff away. This means all the content also has to be changed/updated/added to plus we are progressively moving to active on-line databases, which means it will be some time before it is all complete. It is active, though, and can be accessed via the MOP portal above.
Those new systems incorporate all the ship related options so the old section is already redundant. In all the other affected sections of the site a new link takes you to the same login screen. The old genealogy files are being offered for downloading rather than being displayed on the site directly. Download the file of interest and IMPORT it into your own genealogy program.
