I just want to reiterate SStallings' and Coe's points about making the forum the most useful in terms of finding the topics and information one is most interested in. If a topic is hijacked, one of the effects of that is that a new discussion can take place that might be very useful but is not indicated at all in the topic heading. It would be much better, IMHO, if a new topic were started so that others can quickly see what is being discussed. I'm sure I'm not alone in that I don't have time to read the vast majority of threads or posts. I get online and quickly skim the topic headings for stuff I might be looking for or that I might be able to help with. "Buried" stuff is usually lost on me.
On a closely related subject (dubiously mentioned here instead of posting a new topic on this, I know

), I wish everybody would make the headings of their topics clearly state what the topic is. Headings like "need help" or "guess what happened to me today" are very common and give us zero information about what the topic actually is. That's frustrating to me.
