Thanks, FE, for raising this. As you say, it is timely as you we have seen an increase recently. It is quite annoying and it doesn't do the poster any favours vis a vis getting their thread seen.
While we're on the subject, what about the increasong number of duplicate postings? It's unnecessary attention seeking, it's not fair on the people who post one question in the correct section, and the responses get split between the two posts so we risk missing the full picture as a subject develops.
