The thread got renamed. It is now: Lyr Req: Is My Team Ploughing (A. E. Housman). (I figure, in the long run, people are more likely to find the thread if it is correctly named.)
If you can't find a thread by its title, the way you remember it, you might try using the Discussion Forum Enhanced Search, accessible through the drop-down menu at the top of the page. Then use the subject filter.
When thread titles get changed, the message titles (subjects) usually don't get changed.
Sorry for the inconvenience.
