Thank you very much for the comprehensive instructions in the use of the discussion board's search engine. These technilogical advances continue to amaze and astound me.
Alas - if you had paid attention to the question at hand you might have realized that finding the discussion thread is not the problem. The problem is that pages of the discussion (beyond page 33) have gone missing, disappeared, vanished, hidden, invisible, maybe even kaput!
Now this would typically indicate a number of possible problems. Indexes in the backend database may have gone awry, the hard disk storage devices may have developed bad sectors impeding data retrival. If served by a non-RAID-disk array a single hardware component could have failed. The underlying code which enables querying of the database could have incurred corruption. The servers could have memory limitations. Someone may have accidentally or deliberately deleted or moved the data. Hmmm, I've likely missed a few possiblities but let me thank you again for those comprehensive instructions in the use of the discussion board's search engine. Gee these technilogical advances -- they are wonders.
