OK, this is just a very personal feeling, but I'm not a huge fan of reviving threads that are over a year old. I think it's great, though, when a new member re-sparks an old thread by starting a new conversation and providing a link to the old thread that inspired her.
Two reasons for my feelings: First, old threads are often revived by spanners whose spam is immediately deleted. Once the thread lands on the front page, though, it's indistinguishable from new threads unless we pay close attention to the dates, which most of us probably don't. That leads to helpful responses being offered to people who are no longer on the forum or whose "problem" is no longer in existence--thus confusing everyone.
Secondly, I think it's somehow bad manners to revive a thread when the author, and many of the respondents, may have chosen to leave the forum--or if the circumstances under which questions and comments were made have changed. I just think it's safer, and sometimes more tactful, to re-introduce on a fresh note.
But these are exclusively my feelings and may not be shared by others. I know Angie and Greg have chosen to leave all threads active, and, as administrators, they set the rules. So I don't think you are violating any etiquette by reviving old threads, Angela.
