I've seen several long threads lately where newbies ("jr. members") and "members" have been posting questions that have nothing to do with the main idea of the thread. I see this a lot in shorter threads too.
If you want your questions answered, you'll probably get better and quicker responses if you start a new thread instead of asking a question at the end of an thread whose title has nothting to do with your question. By creating your own thread with a good title, your question will probably be answered quickly, AND your question will get the attention it should.
