LWAG has not been updated for a long time. It was owned by Richard Eger who passed away. It would be a significant loss if messages posted there cannot be recovered.
In a similar case, the Luftwaffe Experten Message Board (LEMB) contains significant information. I can still access it by using my original log-in. But it effectively closed some years back and exists only as an archive.
Perhaps the owner of TOCH! should consider writing a will to someone who can continue operating the site.*
*Hey, as much as I refuse to admit it, I've gotten just a little bit older. Not by much
