Apparently, the Search as implemented only allows Member names for threads to be searched and does not include guest names, thus making it impossible to search for all of the messages in one thread by a guest with a name. The need for this is obvious if one wants to read all of the posts of a named guest without having to scroll through one thread from from start to end. The thread for Guardian Rom contains the guest named x492 for which my Search failed. Why not expand the Search to include the guest members with specific names so this can be done? -- Tom
