Thanks so much for pointing that out. From now on I’ll resurrect threads from the Paleozoic era instead of starting a new thread.
If the old thread is perfectly relevant to your topic, then resurrecting the old thread (rather than clogging the board with a new one) is actually the usual messageboard etiquette. Some boards are pretty harsh on users who needlessly start new/duplicative threads. This one is more relaxed about it, I admit.
