Can anyone find out…

I was speaking to a friend tonight and I by chance bought up this forum in conversation…I happened to mention the word association thread and she remembers a forum she had viewed which claimed to hold the record for the longest forum thread and had been entered into the guiness book of records.My friend and I have been unable to find the said forum and are having great difficulty in finding an entry in the book of records.Does anyone know of this record and what it stands at?:confused:
