What I was suggesting was that should I see a thread heading post that seems to belong in another thread I could link to the thread in my head while reporting it.
For example
If someone were to make a new thread about what they hate about the EU I could notify a moderator that there is already a thread covering that topic and point them in the right direction by providing a link to where I think it should go.
The end decision being the moderator's,
natch.
