Thnaks for the information Wayne and good luck migrating the site.
If Amiga.org requires a "re-boot" then so be it. It's the people here who make the site worth visiting, not the legacy pages held on the server.
I'm a regular member on another site that had to do something similar. They mothballed the old site and made it available as read only and then carried on with a fresh, new site. To be honest, despite the initial "shock", I don't think anbody was bothered after a couple of weeks had gone by.
