On another forum I frequent a guy just made a post in a thread that's about four years old. It was a short question, with a short answer and a couple comments...and one half of the original answer was wrong. The guy found the thread because he had pretty much the same question; searched and found that thread...then found out from experience that the answer was only half right.

Some forums I frequent that would be met with a totally draconian "do not necro threads" response...but I think the guy did the right thing. Anyone else with that question who searches would run into the same old thread with the same wrong answer, so not adding a comment to correct it seems pretty much counter to the idea that a game forum is a repository of tips and advice. If he made a new thread people might find that instead, but they might also find the old thread first and think they have the answer so stop looking.

Thoughts?

Just start a new thread if it's that old.... And don't believe everything you read on the internet.

To me, reviving an old thread is perfectly fine. Necro'ing is not. To me, necroing a thread is just posting in a 5-6 month old thread with 'lol' or 'I know right?' as posts.

Agreed, honestly some people get a bit too anol about Necro'ing threads but for the most part bringing back an old thread with a valid post is fine.
