I spent about 6 hours going through the forum menu for March 30 that I found at archive.org. I then used the Filter to search Mudcat for each thread. If the thread had not been posted to since Mudcat was restored, there was a good chance I could find an intact, cached copy of the thread at Google. I then logged out and posted each message as a Guest with the original poster's name.
It's tedious, but a fairly good process.
But if the thread has been posted to or an new thread with the same name has been started, the Google cache of the missing messages disappears - so it's important to do this process as soon as possible after Mudcat is restored.
Does anybody have an idea what's the time period where the messages are missing?
