What I meant is it possible to verify that the thread actually exists or existed. Perhaps go to a solicitor ask them to go the website and print and stamp it. Or maybe a public library, and get them to stamp it. An honest broker of some kind.
I take on board that the content might be spurious. However, there are several people in the same situation as myself, that posted their experiences prior to my situation becoming an issue. So I think the thread could back up my case, in case of a legal dispute.
